Your first paragraph doesn't contain any content, it basically says "Well yes, OK it's not a problem, but that doesn't mean we should allow it".

The third paragraph is basically trying to backpedal into suggesting that you need to be "fully female" (presumably you mean presumed female at birth) in order to qualify as a woman - this is clearly nonsense, as plenty of women - that you would accept as cis women - do not possess all of the traits that you have uniquely deemed to be feminine. Your suggestion at the simplest level erases butch women for example. It also excludes lesbians, since it could be argued that biologically attraction to a woman is a male trait.

Your attempt to try to rationalise your transphobia actually works against you.

Your last section tries to justify trans exclusion and laughingly claims that it's not a "human rights violation". The problem with this reasoning is that it requires a premise that "trans women are men" in order to follow: Trans women are women, and to say otherwise is to deny the dignity of their existence, which IS a human rights violation.
