How is that gay women and men are looked at like perverts?

I have recently noticed especially being now fully involved in the women's lesbian community that many people almost get a bad taste in their mouth when they hear the word \"lesbian\" or \"gay\" and it makes me so frustrated. as a woman who Is bisexual. I feel almost discouraged and half a woman. that because I'm not the cookie cutter mold of what America has made, that I'm not a full woman. And as well as having been referred to as a child. I am 20 years old. twenty,in other countries 20yr olds run a household, find food and bear children but me being of a different orientation and comfortable with myself at 20, I'm a child? I just didn't understand. I had an ex boyfriend,(emphasis on ex) who said because I was a woman ,he had to and was trying to get me pregnant I had to cook, clean and stay at home and raise babies. Me working was out of the question. i want to change men's way of thinking even though I know some or most of these men were taught from childhood that this is how men and women relationships work. but that's not how it is now In 2014. We have women CEO's of billion dollar companies. ugh sometimes I just get so frustrated an exhausted by it all.
