Look around the thread at how people are treating each other, and then keep in mind that HN is probably like 99th percentile for civility on the Internet in this regard.

Look at what happens in threads about any other politically charged issue, for that matter. Heck, look how far the discussion will veer into politically charged off-topic matters, whenever the OP is about some meta-level "how to be convincing" "how to argue fairly" etc. point.
