Unfortunately, far too often, the opposite happens, people decide to dislike something and ignore anyone who says otherwise. This is not a mental illness (though sometimes I think perhaps it should be), but Stockholm Syndrome certainly is. You also have continued to ignore any counterarguments to your point, So I have to assume you agree with them. We have already established that gregtech is not grindy in any way, and that long wait times only serve to encourage automation.Cognitive dissonance isn't a mental ilness, it's how our brain tries to reason towards decisions we made. Some people just don't seem to be aware that this happens. This is where a lot of the mindless fanboyism comes from: people who have decided to 'like' someone in general and then reason everything about that thing towards agreeing with it.
More intelligent people just know this happens and know that to have a proper discussion you have to take this into account.
