Unfortunately to many, everything is a team sport, and that isn't an accident. It is a result of decades of carefully crafted propaganda by the powers-that-be. It's why otherwise intelligent people repeat idiotic tropes like "echoing propaganda", because a designated bad person says something, by definition that statement is false and making any similar statement puts you in league with that bad person and makes you bad. It's also an easy way to dismiss objectively factual statements and arguments without substantively engaging with them in any way. The same goes for appearing on outlets that are considered to be on the other team, working with someone on the other team on an issue (even if that issue isn't itself objectionable) and even talking cordially with members of the other team. It is an incredibly useful way to keep people on board with whatever team play is called by the team owners and also keep them from developing or expressing any independent thoughts whatsoever.
