I haven't read the 6 pages of replies, but IMO it isn't that hard to understand.
In thise case religion does not equal morals. It means talking about religion! Debating what group is better, atheism, etc. Talking about the best way to kill a rat, imo, has little to nothing to do with religion.
Same with a new law... saying "proposed law will punish sex offenders more strictly" or whatever is far different than saying "George Bush is a moron".
The threads that are deleted/banned are the ones that have/will turn into an argument. I don't think a post about a proposed law to ban snakes somewhere will create a huge flame war... but something about liberals vs conservatives will.
I don't see any ambiguity here.
