Lack of community and atomisation of the population into profit-units for industry. There are a few very specific avenues for dating "discovery" and if you don't fit into them you don't fit into reproduction within the modern hyper-capitalist landscape at all.

I will in fact blame television for the first wave of this problem, followed by videogames. The takeover of "entertainment" by these two industries took entertainment from being a social thing that occurs outside of peoples homes (or shared through visiting each others homes) into a compartmentalised thing in the house. The things outside still exist, but they exist in far fewer forms and far less variety than previously, meaning that there are fewer ways for people to discover one another and there's much less "come round my house" where closer bonding occurs outside of a public setting.

Everyone here is focusing on the "men are the problem" issue and not on the fact this is a systemic issue that has grown as a result of modern society and amenities. It even exists in far earlier forms in global south countries because these forms of entertainment have not yet taken over communities due to lower levels of accessibility.
