look you're probably a nice guy from this response but you can't cave in like this to defuse an argument.
To be clear: I agree with your statement that fans who don't take the time to learn about the team they're "supporting" are generally bad and create negative experiences for everyone.
This isn't my argument nor do I agree with it. I think fans who don't take the time to learn about the team they're supporting are simply dumb and I'm calling them out for it, I don't think they're generally bad nor do they create a negative experience to anyone really unless they actively do so, like them going out of their way to make fun of other teams and how their team they're "supporting" is way better n shit like that.
I'm guessing that you probably don't actually agree with the statement you claim to be agreeing with to sort of end it all on good terms, but you don't need to lie like that.
