I noticed that there were people who disagreed with my argument, but nobody who bothered to offer any kind of rational, logical, counter-argument.  Why is that?

I'll tell you why.  In our society, in the realm of politics, it is perfectly acceptable to say "I disagree" without offering any kind of explanation or argument.

But think about this for a moment.  If I were to say "white is the supreme race, that is my opinion," wouldn't you question that?   Wouldn't you demand an explanation?  Would you be okay with just leaving that as "my opinion?"  Of course not.  You would challenge it.  You would say "that's wrong, here is why."

That hasn't happened.  Why?
