This actually came up yesterday in a staff meeting at the game store I volunteer at. Luckily, I have found a diverse local game store and the staff there is extremely supportive. I've been to more than a few where that wasn't the case. The scene is getting better every year, and the Magic community seems pretty committed to making sure organized play environments aren't hostile to anyone, but being treated poorly in the past is the number one reason casual female magic players say they don't want to come to events. That's sad. Games are fun, and girls shouldn't have to be harassed in order to play them.
