YES. I was actually about to bring up how being a girl just makes it even more miserable, but I would have started ranting too much. I'd just love to direct these people to the nearest time machine, and bring them back where they belong, because they most certainly don't belong here in 2016. Not with all of us frightening girls playing video games running about~ :3
As for Pokémon, I can imagine how awful they must be, particularly at unofficial competitions. I've completely given up on discussing battling publicly online because of how instantly-dismissive and closed-minded so many people are.

Also, they always assume that you play "Smogon-style" singles. Not everybody does. I play "official-style" doubles, with the "official" banlist of only major legendaries and mythical Pokémon. (The same Pokémon that are banned from in-game facilities like the Battle Maison.)
I'm not so sure about the atmosphere at official competitions hosted by the company, though. I've always been under the impression that they at least make an effort to keep things pleasant.
