The only "Alt-Right" collaborator I know of is a Joe Biden supporter who perpetrated the Charlottesville massacre.[1] Of course, you could try to refute any of the evidence Ngo supplied in his tweets, but since you have nothing yourself, it's much easier to call him names, slander him and generally resort to FUD tactics, ad hominem and guilt by association. If you could actually refute anything Andy Ngo reported (and for all I know, maybe there's plenty), then go ahead and do it. It would be irrelevant to the particular claims I was citing, but at least it would be informative. What you've given us so far is an over-the-top innuendo narrative that is so sleazy even your average MLM salesperson would cringe.

yeah dude, tell me more about this alleged "slander" of Ngo, no dude he's a grifter, that's not "FUD", that's old news and not really controversial.
