So, there are people who disagree with what you posted, and may be inclined to argue about it. That, combined with the idea shared in the Paul Graham quote in this very thread (about politics frequently being used as a form of identity) leads to defensiveness, leads to rationalization, and leads to stupidity.
So, in order to avoid stupid arguments, people would prefer fewer posts like your quote on LW.
