Of course people on Smogon rag on Deck Knight while supporting groups that say things just as bad as him. It's the cool thing to do on Smogon. No one points out the shit that the groups you mentioned say because it's much easier to just believe it and to hate on feminism.
To be frank, I call melee fast-paced not because of the metagame but because of just how fast it feels. Brawl is too floaty, sure, but melee just feels so jittery that it looks like it's being viewed through a fast-forward filter. But I DO prefer a meta where positioning is rated higher than speed, though.
