I didn't equate conservatives with neo-Nazis. Try reading more carefully. I think stories like these are a waste of time, but I looked into it since you brought it up. The suggestion that Gorka is a neo-Nazi is no more (probably less) valid than the suggestion that Khan is an Islamic extremist.
I will say that Gorka was asked to disavow his associations and Khan was not. Now, Khan shared a stage with a convicted Islamic terrorist and has a number of other troubling connections. He was not asked to disavow these connections, to my knowledge, and certainly not, I would hazard, by a mainstream medium.
Perhaps neither of them have substantial connections to extremists. My point was that one was asked for a disavowal and the other was not, and this is where the partisan bias lies: conservatives are painted as if their connections are insidious, while liberals with potentially (more) insidious connections are left unchecked, and conservatives are asked to disavow such potential connections while liberals are not.
I didn't equate all leftists with SJWs. SJWs, however, are quick to say things like "all Trump supporters hate black people," something I heard this past week. I will say this: it makes one wonder whether the blacks who voted for Trump hate black people as well, and if so, how this all makes any logical sense.
(And to your last point, as an aside, "established" networks like CNN are predominately fake news. Weapons of mass destruction? Cutting off people when they say something disagreeable? "Is Trump afraid of stairs?" CNN and other "established" networks are and have been for years tools to spread propaganda. Read Adorno and Horkheimer's The Culture Industry: Enlightenment as Mass Deception if you want more background, for it is far too much to explain here in brief. There is plenty more to read as well, if you're interested in broadening your understanding.)
