I found the post you replied to very incongruous, because as I read it started with the idea that men are casually discriminated against (responding to the "men suck" thing) and then skewed into something that may be an issue but is completely in a different spirit (men defying stereotypes by being primary child carers) and then committed exactly the same offence the original post was pointing out with "toxic masculinity". It's almost like a weird simultaneous attempt to find victimhood while still toeing the "men bad" line.
The post said "female dating pool selects in favour of features that are often red flags for toxic masculinity". I took that to be a pretty expansive definition, typical "men that women like over me are toxic" vibe, at least that's how it comes out.
