Hey, im a christian but im also a lesbian, and i know how they feel, if their like me theyve grown up in a house where if they do or treat people they wish to be treated they could get outcasted, its not so much that they hate you their just scared. Maybe have a friendly talk and expain things to them, but make the point that your not here to attack them, you just dont feel comfortable :)
if you get aggressive they might also get aggressive
