On reddit I typically ignore them as nearly all are either bots, paid propagandists, or Nazis themselves who are stupid enough to think they're going to change someone's mind. But Lemmy is a whole new ballgame, and if the poster IS one of the above trying to be sneaky about sowing doubt, I didn't want to leave the comment unchallenged for others to get the wrong idea. I mean this whole post could have just been left at "Putin said..." and most of us just have a good laugh and move on. :-)
