I'd be more surprised if people weren't bitching, to be honest. ¯\_(ツ)_/¯
I never understood this. Why shouldn’t people bitch? In a fandom as large and diverse as Star Trek’s, the odds that everyone agrees about everything are none. Naturally, differences of opinion will arise and lead to strong emotions. That’s human nature. Airing those differences on a Star Trek forum? Heaven forbid! What should we be talking about? Who the actors are dating? Come on. Bitching is half the fun.
