I would like the SE community to vote on reopening this question: How to deal with a coworker who makes hateful comments about my religion?
I felt this original reason for being put on hold was the focus on the comments made on social media which is indeed off - topic for The Workplace. My edit a few minutes ago re-focused the question on the work-place and the OP's desired outcome: To have the offensive behavior immediately cease. I also addressed why the OP would like to speak up: Because he finds the behavior offensive, unprofessional and wholly unbecoming of a coworker in a professional workplace.
I am not able to add an additional answer due to the question being on hold.
