When people are starting to go around and imagine what's going on in other people's heads, it's gone too far beyond "criticism" or "feedback."

If you cannot distinguish between that and "regulating what other people think and feel", anti-Semitism, homophobia and McCarthyism, then maybe you should rethink your own lack of perspective.

One horrible thing about being gay-bashed, and I have experienced this personally, is having other people talk about what's going on in your head, as if they know better than you. There's something particularly dehumanizing about it. Such things also come into sectarian bigotry and out-grouping. I've even experienced a bit of that from being raised Catholic, though that sort of thing was much rarer. Certainly McCarthyism involved a lot of this speculation about what's "really" going on in your head or other people's heads.

then maybe you should rethink your own lack of perspective.

Having been the recipient a lot of bigotry in my lifetime, one common pattern I've seen is people arrogantly, confidently, even self righteously jumping to conclusions about what's going on in my head while being spectacularly wrong. I think that's quite a profound perspective. It's also a perspective which is the foundation of caution against people who use phrases like "maybe you should rethink your own lack of perspective" in such a gaslighting fashion.
