So now you don't understand logic or biology?

Quite the contrary, I think I have a reasonable grasp of logic, having taught it.

I joined this thread on the assumption that polite and reasoned debate with other participants was possible and preferrable to insults.

Oooh, too bad for your students. I too had teachers who thought they understood a subject in spite of the obvious.

Polite, okay, even encouraged. Reasoned? You have yet to demonstrate that you are capable of that ...
