Looks like someone isnt a big fan of leftist articles, lol

But it was probably because of the feddit-dbzero drama post lmao

It's also just kind of a silly thing to implement in a client. That's the perspective the memes are coming from. Usually, blocklists should be left to the instance administrators or users. The client should only easily allow such a list to be available.

Like apparently it's not "leftist" per se (or trans or furry etc.) so much as extremist rhetoric, or even instances turning a blind eye towards same, for the sake of mainstream normies coming here from Reddit.

It would be like blocking pretentious people, then vegetarians decrying unfair/biased treatment.

Note that many leftists are not blocked, like I strongly doubt that slrpnk.net would be, it's primarily the more "militant" varieties.

In other words not hard-coded at all.

PieFed is quite opinionated, and the instance picker even more so, but the "hard-coded" arguments have long since been debunked (though last I checked, without being acknowledged by those who initially spread the story).

Also the flagship instance PieFed.social does block a lot, but that's as different as an instance is from software. Btw Lemmy.ml rather famously blocks a lot of content as well.

Whatever software you use, pick good instance admins that you feel reflect your values (or even self-host your own), and you'll enjoy your experience on the Threadiverse much better than being at odds with them.
