It’s more like:

“All loneliness epidemic” == “All lives matter”.

You don’t like a particular demographic and then you invalidate their particular problems saying that everyone have them.

It’s exactly the same argumentation. We all know that really all lives matter, the same we know that people is more lonely in general. But the same it is a specific problem with US cops killing black people disproportionately compared with white people there is a problem with men being more lonely in relation with women.
