This is the oddly standard wording used in defense of these newly-fashionable 'everything you've ever done ever can be used against you' contributor codes of conduct and I have to find it very disingenuous.
By and large nobody wants to exterminate anybody. People have legitimate differences of opinion and when they attempt to express them they're being told that even _thinking_ that opinion is tantamount to violence.
If you can't see it as anything other than a transparent attempt to restrict discourse I don't know what to tell you. It isn't like this is the first time this strategy has been used.
