I was born in the rural midwest and lived there for almost 30 years of my life. Not once have I ever heard of anyone receiving the treatment you claim to have received. Not once have I ever seen anyone receiving that treatment. Therefore, I'm inclined to believe your wild accusations that are so far outside the norm are some Jussie Smollett level incarnations unless you have verifiable evidence.
Since I have the experience of multiple years in the midwest and you were just briefly visiting means my anecdotes have more weight. Just like I wouldn't trust a person from London to provide an accurate representation of life in the Congo I also do not trust you to provide and accurate depiction of life in the midwest.
I live in CO now. I heard the N word multiple times coming out of white student's mouths here. So, I'll just go ahead and make an unfair blanket statement and assume the entirety of the western US is racist scum? NO, because I'm more intelligent than that and not a prejudiced bigot that assumes one person or a handful of people represent and entire area of the country.
Take look at your responses. You're the one painting an entire group of people negatively based on one experience and we have online proof of it. That is the definition of bigotry.
