If you’re just using social media for entertainment, I don’t care who you block or how. But perpetuating the idea that “follow equals endorsement” is a problem regardless.

This has less to do with people having a right to be seen and more to do with the perpetuation of ideas that make society more polarized in spaces where such things matter.

To put this another way, I’d react less strongly to “blocking people based on who they follow weeds out almost everyone I don’t want to see and I accept the false positives”. I’d still express concerns about the resulting echo chamber but that’s a far more reasonable position.
