If bluntly disagreeing with progressivism makes you blame-worthy for mass-murderers, well then we should throw all conservative media hosts in indefinite prison. Or execute them.
"The extent of some liberal ideas" is a really soft way of putting "open racist and transphobe" He literally did a segment on the "Great Replacement Theory".
He's a white supremacist. He can get absolutely, thoroughly, and without lube, fucked.
Tucker Carlson thinks that immigration is ending the white race. That's a direct quote, go watch the segment.
I didn't hear this "direct quote" of yours anywhere. Tucker doesn't mention the "white race" at all, he speaks about government policies and how they influence native population growth (Americans born to Americans), and about the rate of immigration. If I missed your direct quote, then please provide a timestamp. While I find many of the supposed factual claims there debatable, this argument that too much immigration can be destabilizing is not obviously false.
What I've seen time and time again in situation like this, from both sides, are claims of "dog-whistling", wink-wink-nudge-nudge "we know what you're really talking about [insert-person-I-hate]".
I'll also note that "demography is destiny" has been an unofficial Democratic party tag line for decades now. The notion that Democrats have more vested interest in increasing immigration is not exactly a conspiracy theory, although given how the Latin population is now leaning Republican I think they're realizing that that tagline is deeply flawed as an actual strategy.
Here's a short one minute blurb, should be digestable enough for you.
"Legacy Americans" "The Great Replacement"
These are not dog whistles. They're not subtle. He's just being racist.

At least I'm not a racist xenophobe.
