Do you feel comfortable making jokes about the Muslim religion?
I feel very comfortable making jokes about islam because muslims are daddy's problem
Not all Muslims are terrorist and not all terrorist are Muslims, terrorists can be of different races even if the media tends to portray them that way so joking about it can be hurtful.
