I am neither trans, nor would I ever presume to speak on behalf of trans people. The reason I posted this is because, over the years, this specific meme has been presented repeatedly as evidence that Klingons are excepting of trans folx.
As such, I think it’s safe to assume that, yes, it carries meaning of (at least some) importance.
In that, I hope my own presentation here is thusly interpreted as an expression of goodwill.
