Whoa, that's not helpful.* We have to ban users that attack others like this, regardless of how wrong the others are or you feel they are.
If you're going to respond in cases like this, please make sure you aren't breaking the site guidelines yourself, because that only makes things worse.
* btw, it also makes moderation a lot harder when people post like this. I'm not saying you need to care about that if you don't want to, but some readers might find it interesting to know: if you think that another account ought to be moderated, the worst thing you can do to inhibit that is to post an attack in the threads.
