If HN is going to actually engage in these political debates (and I question whether it's wise to do so for the community), then people are going to have to stop flagging comments that go against whatever they believe, and just refute them like you just did (using your facts, not your insults).
If you believe (like I do, increasingly) that HN should avoid the political topics, then flag the whole article, not individual comments.
PS: the reason why people use throwaways for unpopular opinions is because they are well aware that there's a large group of people out there who will go after their jobs.
