KANSAS CITY  Mo. â  Justin Houston âs once-perfect team had lost consecutive games after a pair of uncharacteristic showings. The Kansas City Chiefs defense couldnât stop anybody  and the offense suddenly lost its effectiveness in the rushing department  which had served as a calling card during the team's 5-0 start.
 Houston   a seventh-year veteran and one of the longest-tenured Chiefs  looked around the locker room  diagnosed the problem and decided he had to speak up.
âIâm from a big family  so I understand there are times to follow  and there are times to lead. There are times to speak up â  Houston  told USA TODAY Sports after Monday night's 29-19 defeat of the Denver Broncos. âWe just werenât having fun.
And  most importantly to  Houston  and his teammates  the Chiefs had fun in the process.

Q: Itâs always the anniversary of something or other. In November  we have the Russian Revolution and the Balfour Declaration  and this week marks the 500th year since  Martin Luther  challenged the Catholic Church with  his  95 theses. Given the loopy Zeitgeist of our times  I should rush into the street and mark the occasion by defacing Protestant churches with the customary red paint of protest. Luther  after all  was more than the creator of Protestantism. He was also a rotten anti-Semite.
But does  Luther  also deserve a splash of red? The evidence is pretty shocking  not to mention definitive. In 1543   he  published âOn the Jews and Their Lies â in which  he  called my ancestors âbase and whoring peopleâ full of the âdevilâs feces . . . they wallow in like swine.â
 He  had all sorts of ideas for what to do with the Jews  including the wholesale liquidation of their synagogues  even homes  and a ban on the teaching of their rabbis âon pain of loss of life and limb.â
To be sure  Lutherâs Jew-hatred was typical for the time  but  Luther himself  was hardly typical.  He  was a powerful  colloquial writer  and  his  words surely had some effect.  He  was the founder of a church  or a movement  that now numbers nearly 1 billion.
But more pertinently   he  provided a religious imprimatur to German anti-Semitism  which culminated in the Holocaust.  Luther  was often cited by the Nazis  but it would be wrong to blame  him  alone for the murder of 6 million souls.
As far as Iâm concerned   Luther  is a flawed figure. I can appreciate â even applaud â  his  reforms  but they mean little to  me . Nevertheless  I spare  him  the red paint because I know  his  Jew-hatred is hugely negligible compared with the Reformation  he  initiated and  not insignificantly  the role  he  played in encouraging literacy.  He  wrote in German  not Latin  and like the Hebrews  he  so despised   he  interposed no one between man and God. One had to read the Bible.
I pick and choose  my symbolic can of red paint always at the ready. But when it comes to those Confederate generals  they unambiguously stand for slavery  racism and the vile nostalgia for the so-called Lost Cause that prompted the erection of so many memorials. I cherish my Bach  feel bully about T.R. and acknowledge the immense importance of Martin Luther. He did more good than bad.

Q: âThe Honors are the greatest weekend of the year  and it is also the bane of our existence  â Deborah Rutter  said with a laugh. For the president of the John F. Kennedy Center for the Performing Arts  the annual Kennedy Center Honors  airing on CBS on Dec. 26 and honoring dancer Carmen de Lavallade  rapper LL Cool J  television producer and writer Norman Lear and singers Gloria Estefan and Lionel Richie  is a welcome national spotlight on the memorial to the late president. But thatâs all anyone seems to know about the the white jewel box on the Potomac.
âWe really like to think about the other 364 days of the year  and all of the programming that happens on those days â  Rutter  told me in the latest episode of âCape Up.â âWhat I love about being here at the nationâs cultural center is that we have really a mandate to welcome all of the performing arts. It is not just a performing arts center for one assumed art form or another.â
I bet you didnât know that hip hop was one of those art forms at the Kennedy Center and that Q-Tip is its artistic director. âThis is a first â  Rutter  said. âAnd as far as I know  there is no other artistic director for hip-hop â¦ anywhere in probably the world. And weâre very proud to have Q-Tip here leading  guiding and inspiring us.â
While she didnât need much convincing   Rutter  allowed that there could be others who might â for fear of what it could mean for the other arts. âJust because we are bringing in more programming that includes hip-hop artists  it does not mean that weâre doing less dance or less international programming or less of the National Symphony Orchestra â she said. âIt just means that weâre doing more  that we have thrown open the doors of the Kennedy Center  and we are ensuring that all are welcome here.â

There are nine performance spaces at the Kennedy Center that are in use all year. In addition to the orchestra and  the Washington National Opera  Rutter  noted the 46-year-old institution has âa magnificent  world-recognized ballet season. We have contemporary dance  we have jazz  we have a huge jazz series  chamber music  recitals  comedy  international programming.â
Listen to the podcast to hear  Rutter  talk further about the work of the Kennedy Center and how it fits into the cultural life of Washington.  She  goes into what it is like to be the local performing arts center for members of Congress  foreign diplomats and âquite a number of justices from the Supreme Court.â But  Rutter  insists none of those constituencies tries to exert influence over programming.
âHere at the center we have no limits on what we could present â  Rutter  told me. âThe problems I always describe is how to say no  when to say no  and how to not be really  truly overwhelmed by the extraordinary limitless richness of what happens here.â
