It does sound right-wing, but I think it's definitely possible to be left-wing and to want to avoid being a "baizuo". The biggest thing that caught my eye was about "pitying the rest of the world" and thinking that you are a "savior" -- definitely a valid criticism, I think.

The main thing is having a warped perspective.

It literally means "the white left" so yeah, pretty much.

Also not sure what this word has to do with FBI anti-intelligence efforts.

The right wing and the extreme left have remarkable similar attitudes toward the center–to–center-left.

(Leaving aside question of whether the Chinese “Communist” regime is on the left in any substantive sense, rather than merely as a historical rhetorical affectation.)
