"People don't burn other people alive"
You need to acquaint yourself with autos da fe in Middle Ages Europe. Christians did precisely that to women accused of witchcraft, Jews who refused to convert, Christians who were accused of heresy (that is, they held beliefs the authorities didn't approve of), and others. After some Jews rejected Martin Luther's protestant Christianity as not being their cup of tea, Martin Luther suggested locking Jews in synagogues and setting the synagogues on fire.
If that's too ancient for you, only 30 years ago, Christians were raping and slaughtering Muslims in the former country of Yugoslavia.
Last year, Jews living in the West Bank burned down Arabs' houses and mosques, and in at least one house, the occupants were in it.
Terrorists are brutal. A lot of terrorists are Muslim. That does NOT make all Muslims dogs.
If a man from Arvada gets angry at his ex-wife and burns down her home with her in it, are all Arvadans to be considered dogs?
