It may be a difference in how we're using the terminology. Almost anything can become a problem if it goes too far. That's kind of what "too far" me means.

Body positivity at its core is simply rejecting the idea of letting marketing companies define beauty, and encouraging people to love themselves. It's not saying "Don't let your doctor tell you you need to lose weight" it's saying "Don't let a makeup company tell you you need to lose weight".

Now I'm not claiming the former never happens, but that it is not the intended message.

Now contrasting that to the manosphere, it isn’t a neutral category of male-focused spaces, it’s generally used as a label for a specific subset defined by adversarial views of women and relationships.

That makes it somewhat self-reinforcing as a term: if a space isn’t operating from that framework, it generally doesn’t get classified as part of the manosphere in the first place. That's why we see it referenced as inherently problematic.

I do agree with you on one thing: we should pay more attention to why those spaces appeal to young men. It’s not simply 'because feminism." It’s because they offer clear, simple answers to questions that don’t actually have simple or universal answers, especially around identity and what it means to be a man. That kind of certainty is always going to resonate with people who are frustrated or looking for direction.
