Your comments in this thread have broken the HN guidelines by being uncivil and calling names. That's not allowed here, even when you're right—especially when you're right. So please don't do this. Besides breaking the rules and lowering the quality of discourse (yes, others lowered it first, but two wrongs don't make a right), it undermines your argument in the mind of a neutral reader. That's a bad thing to do to the truth.
If you want to prevent me from defending myself against accusations, please delete my account. If you want to defend people calling immigrants rapists that's your call.
Thanks.
Edit: on second thoughts, please delete my account. I don't want to be involved with a website who defends such people.
I'm hardly "defend[ing] such people"; I chided that account more harshly than yours. The issue is simply the rules of the site.
When we ask people to follow the rules, people sometimes think that's for political reasons (i.e. we must be supporting their enemies), but isn't—it's simply that no one is allowed to call names, be uncivil, and so on, regardless of how wrong someone else is. Obviously if we're going to have such rules, we need to apply them evenly.
It's physically impossible for us to reply to every comment that breaks the rules. Users who notice egregious cases that haven't been chided by mods are invited to alert us at hn@ycombinator.com. Obviously, though, the bad behavior of others does not excuse one's own (cf. "two wrongs don't make a right" upthread). And if you mean to infer political bias from the choice of comments I've publicly chided, you'll find that the data (https://news.ycombinator.com/threads?id=dang) sooner support the opposite bias than that one.
HN doesn't delete entire account histories. That would gut the threads that the account participated in, and the threads belong to the community. We do often delete specific comments that people have a reason to be worried about.
