They've been at this a while. They always have to go "no u" because they can't defend their reprehensible shit, so therefore they do nothing but prop up false equivalencies. They know Fox News is shit propaganda, so they pretend CNN is the same, even though it's centrist at best. They know Breitbart is trash fake news (but they still believe it despite knowing it's fake, go figure), so they go around trying to find left leaning sites like Huffington Post to claim those are somehow the equivalent on the left.
That time when they tried making "alt-left" a thing despite that making no sense because alt-right was a specific movement formed recently, not just a descriptive term, encapsulates their whole shtick. They assume, or wish, that because they have something shit that there must be some equivalent on the left because durrrrr that's how pendulums work right? It's also why they try to prop up antifa so much. They can't defend neo-nazis, not without coming off as ridiculous and terrible, so they have to try and drag the other side down to their level with fiction.
