I don’t think so, but let’s check on it: is it a mental health issue when we use an incorrect order of operations in a mathematical statement?
That is simple incorrect logic. What I’m talking about is emotions overriding logic.
Having faith in a religion is very different from justifying emotional reactions with bad logic. You are conflating your personal belief that they are the same with objective reality.
Everyone conflates personal belief with objective reality to varying degrees. A mentally healthy person can process their emotions well and recognize when they do so most of the time. A mentally unhealthy person will not recognize it because of their lack of emotional intelligence.
Again, I am not talking about a clinical condition that inhibits clear logic. I’m talking about the ability to process your emotions in a healthy way.
