I believe this idea is gaining traction based on the historical rates of left-handed people (article).

When being left-handed was a cultural faux-pas there were less left-handed people. When the culture shifted away from beating left-handed people, suddenly the number of left handed people sky-rocketed in the short term before settling at its true natural number in the long-term.

This could be a trend in other invisible culturally oppressed groups, though we can't really know for this meme until neurodivergence is culturally accepted
