sadly in life some people do not have the same view as us and they try to make light of the fact and it comes off as ignorance. every one has the right to worship who and how they may. Our country was founded on this and as a mormon i remember the 10th article of faith.
I to have had this experience of people treating others badly because of religious affiliation. My friends and I were banned from performing n our senior years baccalaureate because we were mormon and according to the other denominations We did not believe in christ. We did not argue with the ministers but respected their opinion and did not perform in the baccalaureate.
As long as you know you are right that is all that matters.
