The initial post in the thread in question reads:

there is a post in the crash section about club members purposly shooting down a trainer with airsoft pellet guns isnt this againt ama code

STL, in that thread makes this statement:

I will confidently, in public, as blunt as I can be, say that in my humble opinion I do not believe the AMA would ever consider flying an airplane in safe manner under the current AMA safety code while shooting a plane with a paintball gun or a airsoft pellet rifle or a shotgun or a 50 cal or a mark 9 no matter what conditions you decide is safe and and not safe, again under the current safety code as it sits today. It's not to say it can't be done with perhaps a waiver or following some kind of guidelines the AMA can provide. Insurance money doesn't grow on trees, it's earned by being safe and SMART.

STL then asks the AMA:

just have a quick question.
There is a lot of talk lately going around about paintball shooting and other shooting at RC airplanes with various guns at AMA sanctioned fields and that the AMA would cover an accident, if something happened.
Is this true?

Maroney responded to the question asked. Then STL tried to use the answer of a generic question about shooting projectiles at models to justify his position about paintball markers. When Maroney responded to the specific question of paintball markers, the answer was, as you should expect, more explicit. Paintball is not and has not been prohibited by the AMA or its insurance company.

If you read the initial thread you can see STL twist with each turn of events, drawing one incorrect conclusion after another.

It was never Carl Maroney that answered incorrectly.
