I think there’s a bit of irony in that the most ‘frictionless’ (and dehumanizing) way to interact on Lemmy might be to hit the downvote button. It’s the thing that rewards the knee-jerk, un-considered reaction.
In a way, the downvote button is the thing that perfectly expresses the demand that one’s experience confirm to pre-conceived notions of comfort - without having to face a response from the person being downvoted - and denies the downvoter the potential for growth.
