Like DizzyDream said, Saturn is somewhere in everybody’s chart.
Now, I will be generous and assume that you mean Saturn is “important” in your birth chart…
Roughly 1 in 12 human beings have Saturn as their ruling planet–that means they were born when Capricorn was rising over the horizon. (Yeah, to astrologers, that’s important). If a full 1⁄12 of humanity was incel, it would probably be noticed. You add in people who have Saturn actually rising when they were born, or are Capricorns or have the Moon in Capricorn, you would be saying that even more than 1⁄12 of humanity are incels because of Saturn.
I don’t think so.
But I have the Sun in Taurus; that makes me skeptical of stuff like this. (lol)
