Saying Donuel's post "verged on incoherence" means the same thing as "I didn't quite understand what he said".

All scientific discover begins with a question. If you're saying one shouldn't ask the questions, you don't appreciate science any more than the uber-religious.

Saying "Do you have to had[sic] held your hand in a fire to know it will be burnt?" isn't pertinent. You trust other people's opinions and experience if you know it will be burnt. You're saying exactly the opposite, as in they've told you your hand might be burnt, and you've replied "bollocks".

I've known people who've claimed to have experienced telepathy. I never have, or I've never identified it as such. It certainly doesn't happen on purpose, so it isn't likely its existence will ever be able to be verified and tested. I think that's what bothers some people most, but there are many things that can't be verified and tested. Many things that HAVE been proven to exist are not proven by direct observation, but by observing what they affect, and one has to know where to look. We average folks don't have what's needed to detect and quantify things.

When you tell people to not ask questions, you're blocking. The lack of anyone's ability to investigate things doesn't disprove their existence.
