I took me a few hours to download the Hanger and Dogfight module which was only 21 GB, and I have awesome internet and yet I was only able to do 2 mb/s at max. I kind feel bad for the people with shitty interent in Canada and Australia or where ever that have to download 100 gb and after that 2-6 gb patches.
If you defend Gamergate, you defend death threats to developers, doxxing of developers, months of continuous harassment of developers (especially those who are women and/or LGBT), and developers being driven from their homes. It is as simple as that. It is a movement born of hatred and spite for women that was bred through a semi-noble (or, at least, believable) cause to garner numbers and it has used that smokescreen effectively to sustain months of harassment and abuse.
Am I saying everyone in the movement is the devil? No. Much like any movement, there are those who follow it for their own, possibly valid reasons or are simply misguided. But moderating on a case by case basis is absurd. Remove the hate group from the site, even if a few babies go out with the massive reservoir of poisoned bathwater.
I hope you realise that anti-gamergate people have also been doxxing pro-gamergate people and have been sending death threats, calling people's workplaces and trying to get them fired just for supporting gamergate. There are many cases of this, they've even threatened people that have used the tag on twitter a few times or the not your shiled tag. And by using your logic, If you defend the anti-gg people you edefend, death threats, doxxing and hate, towards everyone no matter the sex, color or religion.
