I mean think about it, if the media was actually pro leftist, wouldn't we see pushes for actual leftist thought like actual socialism and other such things? Instead, we just get "cancel this RacIsT thing" and "orange man bad" level liberal crap that changes nothing, with anything that supports orange man or leans right being generally censored.
Lets be real, the right benifits the rich, it directly supports them through capitalism, so its obvious they in reality want you to vote as right wing as possible (so long as you dont go too far and vote for an actual populist that is!), so it is only natural they want to make the right seem like the most opressed political group by censoring them on 90% of the media we consume, when in reality the electoral college disproportionately benefits them, they control both political partys anyhow (the dems are just the republicans with more corporate shilling at this point, minus a few people like bernie), and most of our existing policies are right wing.
So, to drive the lie that the right is an oppressed minority, they opress them on the media, without actually allowing any leftist thought to grow either (notice how they still ban things like chapotraphouse, and again, notice how the media always gets mad at microagressions and other pointless shit rather than big issues).
TLDR: The media is a lie made to support the elite.
there doesn't seem to be anything here
