Again, what are your credentials for living and working within different cultures?<quoted text>
What, communities within the USA where you spoke English and demanded they speak English to you?
Given your gross inability to understand people here, constant demands that you know how reality works and everyone else does not, and your odd belief that your age has brought wisdom, though you present none of it, you sure don't paint a picture of someone who can absorb another person's culture.
I can sit down and talk with anyone and have a good conversation. And have. I am not best buds with everyone, but always considered friendly and able to get along with.
Why? Because I come across to them as just people. Just like them. You can't. Your elitism comes across too strong.
You are confused about here. You have a concentration of others with similar mindsets to yours.
