There is a difference between someone committing a crime who happens to be a Muslim, a Christian or a Jew and someone who thinks they are killing in the name of their God flying an ISIS flag. The latter seems to happen more with Islam
Not every Muslim or Christian criminal is a terrorist. Terrorism is a specific crime. The ISIS flag is sending a message
No you (and the media) just ignore all the white domestic terrorist who have manifestors citing christianity in their plights for white ethnostates
