I've read about this, and I can see a number of problems using it in the U.S. For starters, only women who shun MAGA men would make sense. Why shut out your boyfriend or husband if they feel as you do? Secondly, a lot of MAGA men are married to MAGA women, so they wouldn't do it. Finally, a lot of MAGA men might not notice and just figure they weren't getting lucky and never attribute it to 4B.
