The sealion in the original comic is completely correct, which makes me very suspicious of anyone who dismisses someone for “sealioning” and as you say, it usually is just used as an excuse not to engage with what someone is saying.

The sealion in the comic overheard someone being racist against them, and stepped in to say, “Hey, why are you being racist?” And for some reason is wrong because… they’re persistent? Or because they’re annoying? How is that not literally just every “anti-woke” argument?
