Important for what? Perfecting sarcasm skills? Isn't that a stupid way to spend time?
For blowing off steam, and saying what you think.
WP was and always will be the wrong place for that, because there are too many who don't allow that sort of thing to happen without whining to the mods. Other support sites don't necessarily help much either, because they too don't allow the venting that is needed. So at least here we can say what we like, and even if people give it back, we can feel better that we've at least said our piece.
What has happened to you is terrible, and anyone else in the same situation may not have coped. Hell, people have topped themselves for far less. Your family should be ashamed for what they put you through, and surviving that is definitely something to hang your hat on. Your coping mechanism seems to be to lash out at people. If it works for you, well and good. Just remember, that there are SOME good people who might get caught in the cross-hairs, and that not everyone is evil and wants to do harm to you.
