I don't think anything important and productive has ever happened on twitter. It's best just to stay away.
He's got a point, the SJW movement must be stopped, if employers want top talent, fire the people who mob on twitter like this, they're inhibiting great people with flaws from existing, ruining peoples lives so that they can have their short adrenaline infused dopamine kicks.
Be gone SWJs, in all honesty noone wants you, people are just afraid to stand up against you in the same way Chinese and Russians don't stand up against their governments. We didn't elect you to be the moral police. You've got a monopoly on "Internet violence", if the cops acted like you are you would be protesting, but now you're on the side of power enjoying yourselves.
Kudos to this guy for standing up against them, I'm buying that book in support, the least I can do.
