Reading this post, I probably had the typical 'guy' reaction, which was negative towards the post. Why? Because I've been in situations like the ones described, and I wasn't offended and I feel like I'm being attacked for being in these situations that are outside of my control, and don't bother me personally, and that makes me defensive.
I'm not going to disagree that what she's describing is probably sexist, I'm also not going to disagree that she's right when she says this type of thing gets attention.
But I am going to disagree that people think "sexism is entertainment". These types of things are done for the "sex" or "shock" value, not for the "sexism".
What does that mean?
1) Feel free to fight sexism, but stop trying to end it, it will never happen. Instead, punish it.
2) Stop blaming everyone who happens to be in proximity, it's not my fault, I'm not offended, and honestly I don't care that you are (maybe I'm a jerk, but I'm also not a sexist). Instead, call out the specific offenders, I might actually take your side I didn't feel like I was targeted.
