You're correct actually, this is what I get for responding before coffee.

Ultimately, the Overton Window has shifted so gradually right that guys like Carlson are "mainstream" voices in 2021. Established figures in fact. It's not to say that the Bill O'Reilley's and Rush Limbaugh's of yesteryear didn't have their humdingers of opinions, but Carlson is saying and doing things that have moved beyond general crank behavior and well into dangerous territory.

I guess in a more roundabout way, centrists are mostly responsible for allowing the Overton Window to shift as much as it has, on a communal scale anyhow.
