Yeah man. I was also an AMD guy before (now just don't give a damn and buy what I fancy).
I remember before DLSS/FSR people would ask for advice on which card to buy here. The AMD card would be cheaper and perform a bit better, would get recommended but the person would still buy Nvidia (was somewhat bizarre as they even asked for advice)
Now it is more complicated I feel. Upscaling is important, RT also to a lesser extent. That changes things for me as DLSS simply is better. No ifs or buts imo.
Plus these AMD fans as you pointed out can be down right annoying at times. They don't want to be objective and see it as if you are not team red then you are the enemy. And it's like no bro, I have no teams. I just buy whatever I fancy at the time. But carry on like that and you will only sully AMD's further and make even less likely for me to go AMD in the future.
Better to beat people with facts while being pleasant imo.
