You missed the key piece. As I said in my original statement, the thing that makes me call you a fanboy is not that you are "pointing out a factual statement." It's the fact that this "factual statement" has been known for years, and yet you repeatedly draw attention to it. (Never mind that the factual issue doesn't make all that big of a difference in practical terms.)
So the question is Why -- why do you repeatedly draw attention to this "factual statement"? Examine your motives honestly. Don't just rest with "I'm just pointing out a fact, it's your problem if you don't like it." That's superficial.
You're not doing it to be informative, that's for sure. This is well-known "fact," especially around here. You've repeated it many times. Other people have, too. So your motive is obviously not to inform people about something.
I think you like drawing attention to the PS4's "inferiority" to the Xbox X. I think that's why you do it. I think you enjoy putting it down, because it validates your choice of preferred console (Xbox) and makes you feel better. That's a fanboy.
It would be like me repeatedly pointing out that Switch versions are graphically inferior. Yeah, everybody knows that already. The Switch is a less powerful console. So what would be my point, or rather what would be my motive, if I were to repeatedly do that? It obviously wouldn't be to "enlighten" anyone. I'd be feeling good by putting the other console down; I'd be fanboying or console warrioring.
I'm not saying you're unique in this. There are plenty of people around here who do it. I'm not even saying I don't do it sometimes myself. But let's not pretend you're just some neutral observer, "pointing out facts."
