One shared his own experience, the other is a direct attack on his kids and the parent. Quite a big difference. The "I pity your kids" is straight up vile.
Also ironically, you attack with the word "vile" and frame the other comment as an "attack." I can't with this site.
How is it vile to pity children whose parents regret that they were born? Children whose father loathes spending time with them. Sorry, but maybe some people should feel shame sometimes
