sci⋅en⋅tist (noun) an expert in science, esp. one of the physical or natural sciences.

You don't think there are experts in science?

You're somewhat right about 'dentist' as 'scientist' is more akin to doctor, but that doesn't make your overall argument any less silly.

I'm officially going to give up on you now though, it's clear I won't learn anything from this. You can have the last belligerent word.
