Alright, I've had it, I've just HAD it.

This is the second time this week someone has disparaged reductio ad absurdum in a thread in off-topic. Can we please at least get it straight that this is a valid logical form of argument? Stop talking about it like it's a fallacy or I'm going to have to find you and beat you all over the head with a modal logic textbook.

If a then b.
If b then c.
Not c.
Therefore not a.

Clear?
