Sorry to affect your reality shield, but my first line is fact. It’s for the same reason that intelligence totters strongly toward agnostic and atheistic: the unintelligent skew the curve by being strongly religious and conservative. It’s unavoidable: there are more of them.

Medium leans left because writers lean left. Google “media leans left” - gosh, you guys bitch about that constantly!
Again, it’s no prejudice against you. It’s just where the demographics fall.
Unless you support Trump. If that is true, yeah, I and a lot of others will mute or block you.
