NPR is not considered centrist, but left-leaning.
When I check logged out I get CNN and Fox side by side, along with a lot of non-political basketball and Mr. Beast type stuff. Content probably varies on your IP address.
But calling everything disliked "extremist" is counterproductive and is itself an Overton window shift.
For example, does anyone really believe that no abortions, no exceptions, even in the case of rape of a minor is not extreme? We have 15 states right now in the US where that is the case and a large cadre of gop politicians that believe that is how it should be. And not only are those states enforcing this ban, some are going so far as to try to go after people who leave the state to get in many cases, life saving abortions.
I also think that unlimited abortion for any reason up until the moment of birth is an extreme position. Guess how many states in the US that is legal? It's zero.
Oddly enough, when I log out and use a new browser I get nothing but CBC, CNN, Fox, and things like Mr. Beast.
None of which I watch.
I would suggest watching some things outside your bubble. Watch it from the mindset of a poor person who isn't sure where their next meal will come from.
As an FYI, some of the contents of men's rights extend to family court and have an obviously devastating impact on children. Some of those children are boys, whom will inevitably become men. There's also a population of men but not cis men.
Similarly, there is a lot of content that claims to be "feminist" content but really it's just women saying all men are trash.
Both are extremely harmful for gender equality and both tend to get recommended pretty happily by YouTube.
Admittedly, that isn't quite at the bar I prefer. As such, I removed my pointed criticism at the end, leaving the more important and informative piece intact.
But anyone who has consumed a broad range of media today should understand that the term men's rights is generally highly loaded. Just like reverse racism and white genocide.
