If men only date women below 30 (or 27 apparently??) for their youthful appearance, what incentive do those women have to take dating seriously? Those men won’t stay anyway. This is the main contradiction in incel rhetoric. If you don’t like to look at women past 30, women shouldn’t date you “seriously “ while in their 20s.
That’s without joking exactly what they do. Now if that one millennial voter is a different one in each cohort of participants you get huge swings in the survey that are not very predictive of election outcomes, and that error is poorly represented in the margin of error.
