When is it right to demonize people for their religious beliefs?
When is it right to go to a house of worship and yell profanity and hatred toward the religion of that house of worship?
When is bigotry against people due to their gender, race, ethnicity or religion OK?
Never.
D.E. Cantor 
It is NEVER okay to put down anyone for their religious beliefs. Hatred and profanity is NEVER okay either, especially right out in front of any house of worship. It is okay to share with others your faith and beliefs, but NOT in a manner that demonizes theirs. It’s about being respectful, kind, and thoughtful of others. Also, stand up for your rights and beliefs and don’t let anyone do any of those things in front of your house of worship or demonize your beliefs or let them be a bigot against your gender, race, ethnicity or religion.
