Certain posters spam a constant stream of rubbish towards the player(s) they dislike, or the coach because he is "a coward with pussy tactics", whenever things go slightly wrong for Juve, or we get a poor result (regardless of how we play). Pretty much the only time they regularly post.
There's nothing wrong with pointing out perceived flaws of Sami or Bonucci or Allegri, etc., but calling them rubbish, or complete trash, or terrible, or a pussy, or whatever else the geniuses come up with is quite obviously absurd.
Sami, for example, is (in my opinion) no longer a starting XI quality mid in a team of Juve's level and aspirations, but he's a solid mid, very handy in the rotation as a 4th-5th CM, and puts in some very good performances from time to time. But instead we get this nonsense about him being complete trash, an MLS level player, very bad, and we get it every time the team puts in a poor performance regardless of whether Khedira's individual performance was good or bad. And then you get them complaining about group-think and not being allowed to have a discussion about Khedira criticizing his faults (never-mind the fact that the majority of the forum criticizes Sami from time to time). Everyone knows their opinions on Sami, half the people they are complaining about have tried to discuss Khedira's qualities in response, but they respond by returning to calling the player trash, which isn't criticizing his faults and certainly doesn't foster the discussion they claim is being stifled.
And this is why they get ridiculed for such posts and the reason why people defend players like Khedira. A player who has contributed substantially to Juventus' last 3 domestic doubles and CL final run in 2016-17. Somehow they still fail to acknowledge that Khedira has any positive points as a player or has contributed to Juve at all in his time here. It's silly.
