Okay, fair enough.
But I think you make several cardinal mistakes about my inquiry. One, and this is the most common, is equating questions towards transgender identity to be on parr with inquiries of race and/or having racist intent behind such questions. The only thing they have in common is identity but they are far apart as the north pole is to the south pole, and why? Because I don't find it credible or very untransparent about someone inquiring if black people are really human that they've got some sort of racist agenda. One could respond: "But could not this inquiry be said likewise about transgender people and have a transphobic agenda?"
Sadly, I'm sure there are some who take this inquiry by advantage to discriminate and dehumanize trans people. But for the record, a lot who question transgenderism are not like this; I'm not like that. I just find it hard to separate gender from sex, and it is a thought of mine, whilst discussing it with others, that if it is okay to state this opinion openly without having to be considered a bigot.
And I'm not knocking five-year-olds. You're right--they do ask a ton of good questions. But when addressing me and using as a response towards me, I cannot help but feel that it is being a little conceited.
