People aren't just commenting on the fact you say you 'politely requested them not to throw shade', but your interpretation of what is being said as 'throwing shade'. It could be that you already have some preconceived ideas about other people, and are making assumptions about otherwise neutral remarks or interactions, which then get responded to.
You want to assume that your interpretation of it all is the way it is, and therefore you don't want 'help' changing it, when people might be suggesting that rather than just assuming you are right, and this is how it is, and wondering about why, perhaps all your interpretations aren't right in the first place. It's not saying you have to change if you don't want to, but offering alternative viewpoints about what might be going on, which invariably ends up with the possibility that the interactions would turn out differently if you had a different mindset.
You perhaps don't even think that you are coming across as rude or touchy here, whereas it does come across that way to me. That doesn't mean you need to change - you are perfectly entitled to continue to express yourself the way you like. But it would put me off, if something similar happened in interactions in real life. And yes, that might mean I'd lost out on someone who could be a good friend, because I'd found something rude and abrupt when it wasn't meant to be. Both parties can then look at their assumptions and decide if they want anything to change or not. If you've got all the friends you want, then no need to care, you can carry on just assuming that you've interpreted it right, that it's to do with race, and you can wonder why white women are like that. Or if you aren't happy with things and want more friends, you can consider whether other things might be going on. As can the people you interact with. If I find you rude and antagonistic, but also wished I had more friends, I'd look at my own assumptions and consider that you maybe didn't mean to come across that way.
But it is difficult to discuss a situation that could be based on a false premise, without suggesting ways that things could be different. Many people DO want to discuss a situation because they aren't entirely happy with the way it is.
