My cousin actually plays roller derby, which is pretty cool.

And yeah, I'm interested. I watched a lot of the women's World Cup this year, though I rarely watch pro soccer here in the US. I'll occasionally watch a WNBA game (was super proud when my team the Seattle Storm won the championship), but I haven't for years (I don't watch much men's sports either). I love women's volleyball though, so I'll watch it when I notice it's on (also like watching lacrosse). I'm not a fan of women's hockey though, not sure why.

As for which wave of feminism, I'm honestly not sure. I don't consider myself a feminist so I don't keep up on it, though I certainly support some of the less crazy proposals (e.g. equal pay, longer parental leave, etc). My wife considers herself feminist-lite, and I work with a few women who probably consider themselves feminists (though we rarely talk politics). I personally just prefer more equality and fewer top down rules and don't really associate with any political movement (I'm registered Libertarian mostly to pump registration numbers for third parties).
