Except that it's not true. When you release CO2 into the air,
it doesn't matter where it CAME from. it only matters where
it would have gone if you hadn't burned it.

Yes, it does matter where it came from. In the case of biofuels, the
carbon all came out of the atmosphere, so you are not adding any more.
In the case of fossil fuels, all the carbon came out of the ground, and
you are dumping it into the atmosphere, causing a carbon buildup.

Fossil fuels are biofuels...just not currently produced.

and therefore the carbon isn't current either. Burning it releases that
stored carbon into play.

But where did it come from?
