Of course not; the movement isn't the ideology.
Whatever the ideology, the people in it will be flawed and fallible human beings.
He's speaking of mostly apparent desire, not what people have explicitly said (although it is sometimes explicitly said, too). On the surface it would seem to be political suicide to say one wanted, for example,
- all Trump supporters, or
- all woke activists, or
- all conspiracy theorists, or
- all Democrats, or
- all Republicans, or
- all blacks or all whites or all LGBTQ+ etc.

to be dead. But there is plenty of such talk going around and it is not always cancelled or censored by FAANG and it is sometimes even encouraged. I believe that the OP's observation is correct about a significant part of the population.
Political affiliation and religious affiliation are both beliefs. Wars have been/are being fought over beliefs. There are plenty of quotes by various parties suggesting what should be done with unbelievers at all times through history.
At bottom, isn't everything we know really belief?
My feeling is that the poster is on the right track. Ideological groups, (not trying to pick on politics, but they are usually political ideologues), have become the new pseudo-religions. As people in the West have fallen away from church, we've witnessed the rise of ideologue communities on the right and left.
You can't argue with them. You can't question them. Some want to kill off half the people in the country. Others want draconian control over the other half.
And people are surprised that the only option available to a reasonable person is to opt-out?
If anything, I think people are being shortsighted in viewing the threat. For some people in the US, this ideology war is not only about a right to speech, it can come down to a right to live. Those people have to oppose the ideologues, or die.
I don't claim to know the solution, I do know that it's a tough, tough problem.
