There is a big difference between disagreement and hostility. We tend to interweave the two sometimes, and we shouldn't.
It's fine to squelch someone's opinion with stats and evidence, but when we start including snide comments and veiled insults along with the numbers, we cross the line.
Likewise, if someone happens to disagree with our assessment of, say, Juan Castro's defense and they provide numbers to support their opinion, calling them a stats geek is also crossing the line.
No matter how funny, snarky, or nuanced they might be, these things are still personal attacks and should be treated as such. Be funny and snarky, but don't direct it at other posters.
