I think it has more to do with the puritanical influence on US culture.
The toxicity is not a white thing, so much as a white American thing.
For example, men in Sweden or Finland are as involved in childcare as Black men in the US are. Men in Europe are much more likely to wear pink, eat gelato in public (gasp!), hug their friends, etc. as a result, European men are much less lonely than American men.

So Black men are unique in this regard *In America*.
@mekkaokereke there's definitely a stronger gender balance in Scandinavia and it's spread to some places in Europe, but certainly not places like Italy, which has a dramatically low birth rate partially because women just won't (see also the 4b appropriation in USA, but Italy's objection is more individual than organised)
