I get where you're coming from; it's frustrating to watch the media and fact checkers let leftist lies and misleading arguments fester unscathed while they attack any minor infringement (like this article) or even wholly truthful assertions by the right on technicalities.

I just don't think cranking up the lying, however much it may be justified in a tit for tat sense, is a good idea strategically speaking. Because the left holds the institutional power in the west right now they would just love for the right to really start cranking out misinformation. They'd fact check every lie and, more importantly, they'd heavily publicize every lie. And then they'd use that publicity as the basis for more censorship and more intrusive surveillance, which is exactly what they want to do anyway. It would be playing right into their hands.
