Massive confluence of dysgenics, xenoestrogenic environmental contaminants, absent/inattentive/permissive parents, social contagion, porn induced autogynephilia, meddling from the pharmaceutical industry, moral nihilism, depersonalization from living online, concerted efforts by foreign powers to demoralize and destabilize the west, the vilification of cishet men, grooming by pedophiles, grooming by self-hating liberal "allies", the criminalization of criticism as wrongthink and a whig historian progressive culture that doesn't understand why it's unhappy and constantly searches for "problems" to "fix".
...I think that's everything.
