Many people think being nothing but straight is a sin. Some people even think you should wear certain clothes that fit your gender at birth. Being apart of the LGBT community may make people think differently about you.
Some people think we should wear the stereotypical clothing for our gender we were at birth. They think women should wear feminine clothing and men wear manly clothing. It is a bigger deal for some people for a man not to wear "manly" clothes than for a women not to wear "feminine" clothes.
If a man or women came out as homosexual in the early nineteen hundreds, it was considered illegal. Some prisons even brought physiologists in to talk to the people in jail.
In my opinion, you should be able to love who you love. You should be able to dress how you what to dress. If someones does not fit in your stereotype that ok.
