Quite. It's basically like saying that my protestant neighbor is clearly a pedophile, because there were many reports of pedophile catholic priests, and Catholicism and protestantism are both christian, and that he's part of one of these.
It's quite absurd. You need to really be weak-minded and short-sighted to think this... The Blood Cult was the most independent faith of its times, and only aided other parties (be them realms, like Enweil, or NPCs, like daimons) when it served their own agenda. Everything was done with the intent of wiping off every non-cultist faiths from the map, starting with the actively hostile ones, but eventually very well including Eretzism for which it had no love (but which attacking would be counter-productive, and which would have broken with the policy of letting others be as we build ourselves up, unless attacked first).
We are RPing medieval nobles. Being weak minded is probably the norm really. Also is probably closer to thinking all Muslims are terrorist because a few have chosen that path in order to fight against what they see as injustices against their faith. Or thinking that the goal of all Christians is to convert the "poor stupid fools" to the one true religion, just because the evangelist movements are so visible. We lump large groups of people together unfairly all the time. We still do it today even though in real terms awareness of such issues should be MUCH greater. Given the time period we are playing such things I would think are very acceptable.
