Being trans, gay, bi, black, or a different ethnicity than what is considered 'normal' in your society doesn't make you special, or less than human. I support trans rights and want to treat all humans equally on a base level. Assuming someone who looks or sounds like a woman is a woman is not transphobic, even if they are a trans man. Nor is assuming a man is straight homophobic.
At the same time, I think it's strange to introduce yourself as trans or gay in a public setting or on a social platform as if it's your calling card or occupation to be proud of. I was born with double-jointed thumbs, I don't think I should be congratulated or mocked for that, the same I don't think someone born with a man's body and a woman's brain, or otherwise decides to identify as a woman later in life, or is sexually attracted to either anything or nothing, should be given more than a passing acknowledgement.
I understand the world is cruel and harsh, and so I understand why there needs to be an LGBTQ community, but there -shouldn't- be one.
