They'd remember the general effects it has on younger children, society, and the undeveloped mind. We're discussing this because it's one of the many that show how society views younger men compared to younger women, if it was just a one-time thing it wouldn't be a big deal but these add up and this post adds to the pile. So yes, it does matter when it completely helps the MR movement and also just calls out blatant bad parenting and favoritism
I'm not singling her out, it's not possible to call out every single person who does this. I will happily call you out of someone else did this too. And this isn't doing 'the right job' either, her kids aren't going to end up okay. It's going to ruin their self-view and make them think less of their self-worth.
