Could you explain exactly what that line of thinking is, and why you're troubled by this?
I'm troubled by it because right-wing != violent, and 74 million people voted for the republican candidate. Continuing to disenfranchise their speech options will not go well.
If reddit creates a rule stating “do not threaten or advocate for violence” and in the process of enforcing that rule they find out that certain groups are disproportionately affected, should they continue equally apply the rule or should they start tallying things up to make sure they ban equal amounts of each group?
