Erin Palette has posted six points which seem like they ought to be obvious:
Toxic masculinity does exist, although it’s nowhere near as pervasive nor as powerful as people think.
Toxic femininity also exists, and in greater concentrations than people are willing to admit. I’m prepared to argue this, just not here and now.
The existence of toxic masculinity does not mean that all masculinity is toxic and all men are abusers unless they prove otherwise.
The existence of toxic femininity does not mean that all femininity is toxic and all women are manipulative unless they prove otherwise.
Masculinity and femininity are gender expressions which exist outside of biological sex. It’s not only possible to for a man to be very feminine or a woman to be very masculine, I guarantee that you’ve met at least one of them in your lifetime.
So basically, “People can be toxic — which ought to come as no surprise to anyone — and how they express their toxicity is part of their gender expression.”
Britney Spears, at least, will tell you that toxicity is not necessarily a bad thing.
