> Lunagender, also called monagender, monegender, or selenogender (all of which mean in some way "moon gender"), is a fluid gender identity that changes on a consistent, orderly cycle, reminding one of a lunar cycle.

Not nonsense eh?

This is cherry-picked/extreme. Besides, it doesn't appear relevant if you intended to actually address what the parent referred to as "not nonsense" in the general sense. It's not relevant to what the GP was saying, either.

Explain to me how bisexual is not a choice.

You can very much self identitfy with the now uncountable amounts of genders, pronouns, and cases of mental illness misdiagnosed as LGBT nowadays. I'm not saying gay people choose whom they are attracted to. I get that and I truly believe it. But when people identify as queer, bi, asexual (even though they have sex lol) then its something you're opting into. Clear as day seeing as these people can fluctuate their feelings on a whim.
