The word 'evolution' seems a bit tricky. I do not pretend to understand it fully, even in the strictly biological, non-colloquial sense. In the biological sense, it has to involve, as I understand it, heritable characteristics. If something is learned, say culturally, does it (a) never become heritable, (b) always become heritable, (c) sometimes become heritable or (d) is it not known for certain in the case of at least some characteristics? Furthermore, even if something is heritable, how much does that determine its expression? How malleable (to learning and what are called nurture conditions) are the characteristics if expressed? My guess (partly informed by having a daughter with a masters in genetics and partly by reading around) is that the answers, particularly perhaps for some of the characteristics which are relevant here, are very complicated and the picture incomplete.
So, maybe we can say that we don't know the answer to the question, how much is nature and how much is nurture, but that we might reasonably say that it's a mix of both for most characteristics.
That, I think, is what makes it reasonable to say that certain things can be changed over very short timescales, possibly even in terms of a lifetime. Which I think is demonstrably and clearly true, because people change, and over slightly longer timescales, societies and cultures change, and indeed there is variety in the world at any one time. Sexual, gender and gender politics issues, including the one being discussed here, differ quite a lot between, say, Uganda*, Sweden, the UK and the USA, for instance.
In other words, regardless of whether this or that characteristic has (biologically) evolved or not, that is not, clearly, a good reason to say that nothing can be done about it, obviously. Also 'what is desirable' is not something biological evolution, as a process, is even capable of giving a damn about. Only we can give a damn about it, and indeed 'what is desirable (and undesirable)' is ultimately what we as individuals and societies deem it to be.
Now, because we are a social species, one factor in personal change is social change. This gets us on to social norms, and what is called the 'evolution' of social norms, and of course gender roles and gender role expectations. Excellent introductory article on the former here:
The Evolution of Social Norms
https://www.annualreviews.org/doi/full/10.1146/annurev-economics-080614-115322
(particular emphasis on game theory, but discusses social norms generally)
Something can be deemed or felt to be ok just because the set of social norms allow that (again, see the video below). And things like 'boys will be boys' would be another example. Making comments to, whistling at, even just staring at, and certainly following after women in the street in order to try to engage them in uninvited and possibly unwanted conversation, or touching women inappropriately in a nightclub or social situation, might be others. And yes I would take those things very seriously, even before we get to the arguably more serious issues of physical sexual assault and rape and other violence.
Bottom line: attempts to respond to, deal with, address and/or curtail what is called toxic masculinity (and/or just undesirable male behaviour, if you like) are attempts to steer social norms in a certain, deemed 'better' direction. And I am good with that, and think that we 'should' (and can) do it, and indeed have already, and can do more. And maybe we should set aside questions (that we can't fully answer yet) about biological evolution, and focus on something else instead, something we can do something about. Even if it is complicated, and/or involves hard work.
Or is all of that just restating the bleedin' obvious?
And is also saying that when it comes to bringing in 'what Feminists think' (or 'why Feminism is wrong about this' or even just being non-constructive, or picking holes, being negative, or making objections, especially perhaps because one feels that one's identity group or gender or sex are 'under attack' or being maligned unfairly) and getting embroiled in pointless, repetitive arguments along those lines, that there is a better way to respond? Is that stating the bleedin' obvious too?

Not meant to start a separate discussion. Only meant to possibly illustrate how perhaps the two men in the discussion 'feel it is ok' to speak and behave in a certain way and have certain attitudes, in the context of what they feel are the social and cultural norms of the society of which they are members. In another society, the behaviour, especially of the man on the right, and possibly even the host, would likely be called sexual harassment, and quite possibly, imo, might even be validly called an instance or instances of toxic masculinity.
