Don't know why you would. One is a clear slur, the other describes a condition of detriment that is unhealthy.

I like the Vit A analogy.

There's nothing wrong with Vit A. You need it. It's important for good health. Everyone knows Vit A is good for your eyesight and skin, growth and development, your reproductive system. Not everyone is aware of its necessity in healthy organ function.

But. Vit A is a fat soluble Vitamin. That means there can be too much of it stored in your body. You get toxicity effects from there being too much. Your skin gets all dry and wonky, you get nausea and vomiting, irritable, headaches. You can suffer blurred vision and dizziness; even loss of muscular coordination.

It's unpleasant. It's usually temporary, but it could be chronic.

The touted acceptable performance of socially scripted masculinity can be thought in the same way. (Or femininity, but that's not a widespread problem right now)

Nobody is saying masculinity is bad or evil. Nobody is saying it's ot necessary or zero positive benefits to it.

What is being said is that it's gotten a little extreme in performance and it's become unpleasant, both ad an expectation and to be around.

When you believe you have to be a "barely constrained raging beast monster", as Jordan Peterson says, in order to be validated as a man or have value as a man, or gain status as a man, or whatever....and .maintain that indefinitely, in all situations, then your masculinity had become unhealthy.

The expression of it, like that, isn't good for you or anyone around you. It's toxic. You need a flush, to establish back to a healthy baseline that isn't damaging you or anyone else anymore.
