To preserve the single standard, cut everyone down to size. If you think one voice deserves to be chilled, chill all the others. If the right eye offends somebody, pluck out the left one, too. One censor fits all. All hail to the smiley-face theory of culture.
Churches are institutions.
Like all other institutions, they keep up precious symbols, or icons. And where there are icons, there will be iconoclasts. Democracy, as opposed to theocracy, is duty-bound to protect the iconoclasts. And one thing cops do is protect offensive speech, regardless of whom it offends. So if you think a play is bigoted, you can mount your own, or pass out leaflets denouncing the one you hate.
