I have seen this problem with many people on mailing lists. Without knowing
anything about the other person, they think that the other person is a fool.

The same kind of thing happened with me few years ago and I challenged that
person for a best of five chess games. And I said that if he wins then I
will agree that he is smarter than me. But that person didn't even reply.

I have seen many people who think that they are smarter than other people
but when you actually challenge them to prove their smatness then either
they won't reply or they won't turn up.

Mocking someone is very easy. But proving your intelligence over others is
very difficult.

I never assume that the other person is a fool. Who knows who is on the
other end?

Regards,
Amit
