No reason to say that though. The person you replied to was saying it is a shame it is an emotionally charged discussion and he is right. That one particular discussion on HN might not be emotionally charged doesn't negate his point.
The best way to get an emotionally charged discussion on Hacker News is to put a caveat that it's unfortunate that a topic is emotionally charged. It's a lightning rod and discussion bridge for people who just want debate controversial issues. I certainly have been on both sides of it.
Were you just pretending not to understand?
