Wow... I am not even sure how to respond. Nobody likes an abusive parent, but,... wow. You seem SO angry towards these people, but NOT because they are "bad parents". I question your credibility due to the fact that you posted this about them AND included the names of their minor children. This demonstrates the fact, that you truly do not care for what is best for these children. I do not know ANY of these people personally, but wow. I would be PISSED if someone posted the names of my minor child(ren) publicly on the internet. Seriously, how dare you. It makes me question your quality of parenting. It's not like it was something you did accidently out of anger. This is something sick and twisted. You went through the trouble of finding a place online to post this (and you probably used more than one site) and then you typed out what you wanted to say (which meant you thought about it, was able to read it over, and posted it). Still, months have passed, and you have not felt any remorse to delete your postings, or AT LEAST leave the names of the children anonymous.
God forbid that any of those children try to research their family online and find the horrible things you said about their family. Even if these things are true, it is not your place to inform those children. ESPECIALLY publicly on the internet.
So, if you are pissed off at people accept that, but don't post something under "abusive parents" as if you are truly concerned about the well-being of those children.
