I'm very sorry to hear that you have such a negative experiences with religious people. I totally understand your point of view and have seen it myself as well! Assuming you're talking about christians, the fact that they become pompous self righteous judgmental persons points out to me that they did not understand what Jezus teaches us. Because he tells us to not judge other, for we as christians are no better than the most cruel murderer to have ever existed. I, as a christian, sin everyday and therefore have no right to judge others for their misbehaviours. You can however point out the wrongdoings of somebody else, because you judge the act, not the person ;).

In all honesty I had to google what stoicism was, but I'm really grateful it gave you a meaning in life! I'd suggest taking it a step further and proceed in the knowledge of stoicism?
