I completely disagree and think it's very well defined. For instance in r/nyc I was downvoted for leaving a comment saying how I wouldn't vote for a candidate voting against John Crowley in Queens because part of her campaign is the abolishment of ICE. This to me is idiotic politics (I get that the intention is to move the Overton window to the left) and I was downvoted to oblivion on reddit. Stuff like this is idea suppression.
