Christ, you are serious.
1/ Don't call other people 'asinine', especially on such subjects as this. It makes you look like a conceited twat, especially when you're obviously devoted so little thought to this issue.
2/ No-one was talking about being 'automatically' angry with parents, whatever that word could mean in this context. Rather, that a lot of parents aren't good enough.
3/ You seem to be defining when it is 'appropriate' feel angry by employing very vague terms - 'without good reason', 'victim of actual abuse of some kind'. If someone feels angry at their parents, then you should believe that they have good reason to be. Emotions are not a choice. What to do with them, is.
4/ As for 'the cure is to have children' - not if you're going to deny your own feelings/pretend they're not appropriate and suppress them because, believe me, you will pass it on to your own children if you do that. And that constitutes abusive behaviour in many cases.
5/ "If you cant or dont want to have kids, watching a few close friends/family die should also do the trick." Cos no-one who's angry at their parents has ever also seen people die, right? This is, again, a stupid comment.
6/ I'm outta here. Well done for your extraordinary empathy-free contribution to this thread.
