Except unlike gods, we are quite sure that false flag incidents can happen. Nobody doubts that. The very concept isn't what is questioned, only particular incidents.

I wasn't questioning the concept though, especially as the Nazis used it to kick off WWII in Europe.

But on the other hand, we at least had proof of the false flag attack by Germany. In this case we have, to this point, faith and educated guesses, but it's faith nonetheless.

Putting it on the same level as religion is questioning/ridiculing the entire premise, though I understand that you did not intend it that way.
