Why are you pathologically incapable of not asking questions?

I don't always ask questions. I think you're sharing an opinion, which is fine.

I see.

Anyway, I just want to say that asking for evidence does not work when one is talking about a social phenomenon. Social phenomena involve people and their thoughts, attitudes, opinions and things of that sort. It is simply not possible to get evidence for them because of the simple fact we cannot get inside people's heads.

If you say, "a lot of left-wingers hate Trump", and I ask you to provide evidence, I am being unreasonable. I can either agree or disagree with your statement, but asking for evidence simply short-circuits the discussion.

Wrong question. Correct question should be:
Are There Behavioral Differences Between cultures?

The answer to that is yes.

I will ask any question I want, however I want, and I know this frustrates you.

I disagree. Social phenomenon is observable.

Like the "culture' that is 13% of the US pop.
Yet commit 56% of all murders?

I never said it's not observable. However, just because it's observable, it doesn't mean asking for evidence is now reasonable.

In short. Yes

Why is it unreasonable in this instance?
