Being feminist is definitely about being kind and generous to others, to me and not about saying women are betraying the sisterhood or any kind of competition. It's about fighting sexism, misogyny and just wanting equal rights and consideration, whether your hobbies are shopping, football or something else entirely. I don't think it was a brilliant article though, it doesn't make any original points to me and the prose in the first few paragraphs is pretty poor and the May Queen issue could have been summed up in one paragraph.
I like that it raises the "Cool Girl" thing though from the Gillian Flynn book as that bit really made me think when I read Gone Girl.
I do genuinely like sport and football as I grew up in an avid sport-watching household and my dad taught me to kick and throw a ball, and later out running with him in the same way as he would if he had had a son (I like to think anyway!) And grew up in a football mad area where everyone has to pick a team to support in infant school and stick with it until you die - bit of a foreign thing to DH who, asked which team he supports says he "quite likes Fulham" (sometimes). Also I do genuinely like beer and am quite conversant with technology and gaming (up to a point) among several other subjects...anyway the Gillian Flynn thing made me wonder if I am a "Cool Girl" just pretending to like these things to impress men. Or a "ladette" or "Such a boy!" or other things I have been labelled as (often by other women) in the past.
But you know, I've been married ten years now and I still like these things, and I don't think I need to constantly impress my husband, it's just some things we have in common. And by the way he really likes shopping for himself and on the quiet, is a bit obsessed with shirts and shoes. Does this make him gay? 
So I am not a "fake" though some people who don't know me very well may see it that way. I also notice that some people go through their lives trying to impress the same gender - men do it with cars, Top Gear is the very epitome of this behaviour, women do it with designer or "must have" clothing. I don't get into that, at all, as the impressee or the impressor, and that is enough to really piss some people off.
I guess I just wasn't brought up to think girls do this and boys do that, a pint of beer for the man and a glass of wine or fruit based beverage for the lady. Some people clearly have and it confuses them when they can't put you into a box immediately.
