What has Bob been saying on Twitter? Has he spoken venomously to some people? If so, I'd like to see if they did anything to earn his scorn before kicking up dust over it.
Has he criticized the whole gaming community for the sins of a few? If so, that's worth a bit of reprimand at best.
Are there links to the tweets that put him in the crosshairs?
This entire thing has been a massive clusterfuck; people exploding in frankly startling ways. Someone wants to make a game where the protagonist isn't basically Nathan Drake? CHAOS. Women working in the industry? MADNESS. Speaking out against those who send death/rape threats to people they don't like? ANARCHY.
JUST WHAT THE FUCK IS HAPPENING. This is either about supposed corruption in gaming journalism, where devs will pay reviewers for good reviews - even though it's illegal, or so I've heard - or it's about a sudden internet bar fight erupting because Guy A grabbed the ass of Woman A, Guy B confronted Guy A for being a pervert, Guy A accusing Guy B of only stepping in to be a knight in shining armor for Woman A, then it's just plain havoc.
Then there are people who are screaming that their games are gonna be completely ruined by the 'Feminist Scourge'... How? By having women who wear sensible clothing, who are deeper than 'Look, I have tits'? Alright, to be fair, a more well-spoken version I've heard is, basically, 'games with characters/themes that are only there in a poor attempt to appeal to wider audiences but who ultimately detract from the experience by making it look a bit pretentious.'
But what's wrong with giving the industry a chance to expand a little bit? Give them a chance to do it right, don't just lock them out because you're afraid they'll get it wrong and completely ruin gaming forever, because gaming's more durable than that. If gaming is suddenly dead to you, it's probably because you don't like where it's going, and your opinion will inevitably differ from someone else's.
