men

That you appear to be blind to the demonization of men so rampant within feminism, either willfully or because you’re a victim of its propaganda machine.

Possible. Also possible that you have a wrong understanding of feminism, based on biased consumption of media - fed by algorithms that drive clicks. Unfortunately there is no way to know.

Does feminism ever talk about positive masculinity?

Yes it does, quite a lot.

That’s the problem: they habitually associate masculinity with toxicity.

It does not. You have that association - but I for example don't. Most likely due to difference in media that we consume.

And the characteristics of a gender (what it means to be a man, or a woman) cannot be toxic.

For longest part it was expected from men to defend their honor though violent means? Don't you think that this is not a really healthy behavior? Talking about toxic elements of a gender - people don't talk about biology but about societal norms and expectations. And those can be very burdensome on the individual. You can read about it - right here in this thread, people feeling the burden of the expectation to be the provider for example.

Instead they should be more careful with their terminology and use for example toxic gender expectations. But they don’t. And that’s telling for a movement that is so sensitive to gendered language.

Actually an argument I could agree with you upon. Toxic gender expectation would indeed be a better term.

If you’re interested in getting familiar with our arguments and the evidence, then there are some sources. They are not “random”.

Sure you read Simone de Beauvoir: Second Gender (good introduction to classical Feminism - one should have read, has bit of length like all her works, but is quite insightful) - I go though your links and videos and we meet again in, how long do you need for ca. 1000 pages?, and discuss.
