What's with mc these days??

Is it me or have female MC been getting more and more dumber by the day(especially pink hair ones)?? Like don't get me wrong there are a few who aren't but there a diamond in the rough, and I understand that sometimes you just want to read something with your brain turned off for a bit but like why do most of them have to be like that??! And I don't even understand it when it's an mc who've lived countless lives yet acts like a headless chicken when they are truly needed!! Is it for the ml to shine more??? Or do people just like making mc who are damsels in distress or mary sue's half of the time?? And then when you do find one where the mc is at least somewhat smart she goes straight into her abusers arms spouting that bullshit "oh he's changed" I really don't understand it anymore, I feel my brain cells leaving my fucking body half of the times reading them too
