I have become SO open minded from being trans.
My whole family is racist and homophobic. and I used to believe that being gay was wrong. When I was like 16, I thought lesbians were gross, I thought MTFs were gross (but not FTMs, lol). But that just came from my closed mind.
Finding out I am trans pushed me into the LGBT community, where I became educated about other queer people. and it shook my worldview and I realized that I don't know anything. I got no right to pretend I do.
Unfortunately, my whole family didn't get that experience, so they all still think that they got a right to pretend they know everything.
