Acknowledgment of a parochial viewpoint does not excuse said viewpoint. Acknowledgement of ignorance does not lessen ignorance. If it did, we’d all be prefacing any insulting statement we made with “well, my experience with this is fairly limited, but I’m going to make this highly generalizing statement anyway.”
Imagine is someone said “now, I’ve only met a few black people in my lifetime, but I’ve always associated [insulting black stereotype] with black people in the United States.”
Sure, I prefaced my opinion with an admission of a parochial viewpoint. Sadly, it’s not about to save me from being held accountable(or having my ass kicked) for what just came out of my mouth.
