Because many conservatives watch Fox News, NewsMax, OAN and are conditioned to **always** be upset. Like Pavlov's dogs, they are whipped into an an apoplectic fury at the ringing of the "bells" (fake or greatly exagerated "news story").
You're absolutely right, and it's
exactly just like liberals get enraged by watching MSNBC, ABC, CNN, etc (although CNN is making noises about returning to balanced coverage).
In my circles none of the conservatives or liberals have shown any upset. The liberals are often quite vocal about how evil the conservatives are, and the conservatives are silent.
It depends on the crowd. This forum skews fairly heavily liberal. For a conservative like myself, it can be exhausting or overwhelming to defend a conservative viewpoint in a thread against six or eight passionate and vocal liberals. You get dogpiled in a hurry, and that's not a fun feeling. So it's easier sometimes to just keep one's virtual mouth shut.
That's one of the reasons why, when my teenage kids disagree with me on some deep issue, I'll ask them questions, leading them through a thorough thought process, so they can understand the logic and reasoning, rather than beating them over the head with the Facts of Life.
