I have to chime in on the misuse of a word.
Toxic masculinity is not the gender opposite of toxic feminism. The word I think you're all looking for is femininity, not feminism.
Dr. Peterson started it. He first said (per the Wiki article and subsequent quoting here) that feminism contributed to the threat to masculinity. He continued by positing men were encouraged to be more feminine under this construct, which illustrates his misuse of the word "feminism". This is not how feminism works.
Feminism, is simply the idea that everyone has the right to the same opportunities, having their abilities judged without regard to gender (including men being able to take on roles that society has assigned to women). That is a very basic example -- gender identity should be included in this freedom. The patriarchy is the construct that only cis-gendered men have the right, or should be encouraged, to be in positions of power and influence. Laws restricting women's equal access (or the opportunities of anyone who isn't a cis-gendered, hetero male), per the patriarchy, at best are seen as a desire to "protect" women, and at worst are intended to codify the cis-gendered man's lock on these opportunities.
