I kept my cool and pointed out to him that WotC made her gender in issue when they added affirmative action to their physical requirements and I pointed out that his type of behavior what disastrous for Marvel Comics.
Look I get their point that no other hire underwent this kind of discussion, but most of those hires happened before twitter was as influential as it has become, did not have as much of a big deal made by the company itself, aside maybe for Cook, and it's occurring against the backdrop of certain political interests trying convert beloved geekdom IPs into propaganda for their idealogy, and their way of thinking, at the expense of good story telling and respect for the IP.
So people are more leery of hires connected to an political agenda and had reasonable concern, of course when you get dumped on for having reasonable concerns, reasons concerns over process turn into rage, which leads to more rage on the other side, and then you have a new front in the complex culture war that makes the edition wars look like cuddly discussions between close friends.
And if it's like what happened at Marvel then SJW creators lash out in rage at fans, leading to a hostile relationship between fans and creators, that ultimately damaged not just Marvel, but the industry as a whole, just when it's on the rise.
So yes, Mearls should apologize, or I hate to say this because I like Mearls, he should be let go for the good of the RPG industry. Any culture war front needs to be nipped in the bud now.
