I think most infectious diseases disproportionately kill men because men tend to have weaker immune systems. So, if they want to kill off a lot of men, they wouldn’t necessarily have to make some anti-male super virus. They could just bombard us with pandemic after pandemic after pandemic.

Anyway, after Covid, it’s impossible not to have tinfoil hat conspiracy theories about this shit, and all are on the table as far as I’m concerned. The only only theory I consider improbable is the “official” one from the US government.
