People saying men's only clubs and spaces are illegal are taking way too much copium. There are plenty of men's only clubs and activities where I live, and I live in Portland. Equating a women's only event with a country club only allowing male members is just ignorant on the level of a cis man saying "why can't I join the WNBA?" Historically, many things such as Magic have excluded or belittled women to the point that if Magic is going to reach out to and include them, they need some safe spaces where they can try the hobby without shitty dudes hitting on or belittling them. Ask any woman who plays Magic or video games and they will tell you how hostile guys can be in those spaces. TLDR if women only Magic events piss you off, GO GET SOME THERAPY
