I do not understand why you would describe it as hilarious tbh.
But the hacker scene itself has quite a high and open trans culture. At least on hacker events, camps and congresses like from the ccc, i see quite 'a lot' of trans people.
I agree but HN always seemed more conservative or at least less queer than the "usual", personally I'd have assumed "hilarious" was meant more in a sardonic way, a reverse of the usual than literally hilarious
