(I've not seen any of the usual right wing free speech faction stand up for these...)
Since college faculty often skews 10:1 or better democrat, I don't find that too surprising.
Hi! Part of the right-wing free-speech faction here! (Well, I don't consider myself a rightist, but you probably would.) This incident sucks just like all the other ones! Hope this helps.
It's unreasonable to assume that a right-winger would know about it, just like it is unreasonable to assume that a left-winger is going to know about all the silencing that goes on against the right-wing. It's the media blackouts we're talking about here. That's the entire point.
But to address the left-wing causes on the site, It doesn't actually seem like they're partisan issues unless you're talking about the ones specifically about the previous administration, perhaps except for #22 (which boils down to 'we should tax the wealthy', aka something that was not censored, even if it was narrated against) and #6 which is specifically about a new national news source which is trying to deceive readers by appearing as a bunch of different local news sources. Obviously you might not agree with more but they don't seem to be strictly selecting left-wing articles for this top 25 list.
