The point is that people make generalizations that they don't realize based on their personal experience. For example, I can make tons of generalization about how nice India is for tourists as an Indian (I currently live in America but travel back for family and as a tourist occasionally) but someone who's white might not share that same experience because they might be hounded by scammers and people looking to make a quick buck off of an unsuspecting foreigner.

Similarly, cities and people in the midwest might be great if you're straight, white, and "normal" but that might not be true for everyone. Will people be as welcoming if they see you as an outsider? Maybe. I try to keep an open mind but I also can't be 100% sure.

Oh ok so if I were to say San Francisco might be livable "if you're gay and black and "abnormal" this would be acceptable?

Well, now you're just making things up because everyone knows that San Francisco isn't livable for anyone.

Just a quip here there really aren’t a lot of black people in San Francisco. It’s pretty noticeable coming from Columbus.

Yes but people don't care about Asians because they're white adjacent now. You're right though I had way more interactions with black people when I lived in the midwest.

He's just saying that the Midwest (eg. Wisconsin) is not generally as diverse as Overland Park, which is true. You should examine what made you react so strongly to this.

You should probably examine the comment at the top of the chain he/she responded to and think it over a little harder.
