This incident went way beyond humor and ribbing...Actually, yes...death threats and stalking can be hilarious. It's completely subjective.
There is a big difference for having some criticism about someone's points of view and engaging in a harassment campaign. That you equate the two is troubling.
Once again...what one person calls harassment, another calls humor. Do you think the Internet should be patrolled by humor police?
Women in sports is a huge issue and still is. There are also quite a lot of people who are troubled by the misogyny that permeates professional sports.
Maybe it's an issue for you. Not for me or anyone else that I know. Honestly, I can't remember the last time I heard someone complained about that.
Furthermore, look in any direction...you can find people who are troubled by all sorts of things. Should everybody care about every single thing that a given group of people are troubled by? Should those troubled people be sheltered from humor if it offends them? Do you really, really want someone to police the internet or would you prefer freedom?
The best way to guarantee sexism is never addressed is to not talk about it. The Kickstarter project was about an examination of an issue, not a world-wide solution. That you make it about that is an attempt to move the goal posts.
I don't care about some Kickstarter project. I'm here to say that I like freedom of expression and I don't like it when people start saying there's some sort of big problem because someone else said some words that they got offended by. Boohoo! Death threats make me chuckle.
