I’m really sorry that people are giving you a hard time about your religious beliefs. It’s clear to me from reading these boards that there’s a lot of ignorance and hostility on both sides, and that’s terrible.
I agree with the people who have posted above that first and foremost you must pray. God will certainly guide you in your dealings with these people.
Second, I suggest that you learn as much as possible about your faith, its tenents and history. Build friendships with your coreligionists, and learn how they handle these situations.
Finally, when people make disparaging comments, I suggest you calmly and politely say something like “I’m sure you don’t realize it, but when you say xxx, it sounds like you are insulting me (my religion.) I know you want me to respect of your beliefs and I hope you can respect mine.”
It’s very important that you be calm and polite. You’re an ambassador for your faith, and you surely want to give a good impression. Make it look good!
If the other is persistently rude and/or abusive, you can certainly say that you refuse to discuss the matter further, to the point of excusing yourself and physically leaving the area if you must.
If they want to discuss or debate beliefs, it’s essential that you be non-confrontational. Say “I believe” or “the Church teaches” instead of “you’re wrong, this is how it goes.” Of course you think your view is the correct one, saying “I think” is gentler.
When trying to defuse religious hostility and/or convert another’s opinions, the way you live your life and the way you speak of your faith are stronger messages than the truth and logic of what you say. Think about how you’d like them to behave and act accordingly, and avoid being condemnatory or angry.
In this way, you should be able to at minimum eliminate their hostile behavior and at most, convert their beliefs.
Pax,
