The Left's new hashtag: "#Let Kids Choose"

Democrats, leftists and the rest of the tranny mafia have a new hashtag: "#Let Kids Choose."

See, the tranny mafia claims kids "know" as young as age 4 or so, that they're really the opposite "gender."  Accordingly, it's only fair to let 'em "transition" as soon as they want, eh?

"It's only fair," right?

So surely that logic applies to things other than gender, right?  Like, say...this:

Wait, I hear leftists and others in the tranny mafia saying "WAIT, TATTOOS BEEZ DIFFERENT!!!!"

Explain how it's different, leftists.  Take your time gathering your arguments.  I'll wait.
