It's not his fault.
And I'm not just being facetious either; I have no doubt he is a very honorable guy in his personal dealings with individuals, as are the other conservatives here. But there is something about much conservative thought that seems to depend on their opponents being fundamentally twisted, not just mistaken or incorrect in their political views, but morally or ethically flawed. Except I don't find it tedious, I find it infuriating.
As for "...avoiding a lot of discussions...", that, my friend, is self-censorship.
