It isn’t a male loneliness epidemic, it’s a loneliness epidemic. You’re never going to get satisfying answers to your questions if you accept the framing that it’s a male loneliness epidemic.
It’s a loneliness epidemic for everyone.
Focusing on the arguments of people who have no understanding of the topic and are just spreading toxicity is pointless; but pretending that there isn’t a loneliness epidemic because it’s used to power some incel memes is contributing to the apathy about this issue which is causing harm to both men and women.
