Once again:

The knee-jerk dismissal of a post, based mainly or solely on the lack of a leftist imprimatur of the host site, flaunts inability or unwillingness to engage in independent rational thought.

Classical liberals are routinely censored by the MSM, and by the predominant social networks. These liberals therefore resort to using sites which eschew censorship. It is inevitable that such sites also attract posts by extremists. Consequently, one needs to judge each post on its merits, rather than by a partisan declaration of the plausibility of the post's host medium.

BTW: Rumble wasn't around in 2007.
