Sir, it IS my business because they MAKE it my business when they insist that I recognize them by their subjective identification rather than their given birth gender.  It IS my business when they expect places of employment to do this as well.

See, sir, that is what you don't get.  They make it everyone else's business by expecting everyone else to play along with their mental delusion. If it weren't for that, I would not care and I would shut up.

It is one thing for them to do what they want. It is quite another when people expect ME to go along with it or otherwise play along with their delusions. The minute their mental delusion effects ME it becomes MY business, sir.
