when it progresses into the realm of "4 guys backing each other up that its totally unnecessary and presumably shutting down the SIL trying to correct them," and when literally any research or forethought would show that its a horrible idea, then I don't think it is. It isn't like "can you believe this person isn't 1337 like me" it's "hey can you back me up? otherwise my groupmates are going to tank my grade by being self-deluded arrogant pricks". It's the not listening when being told why its a bad idea that sucks, and the sexism aspect, while this is way too 3rd hand to know for sure, is pretty sus from my experience in comp sci circles
