What is factually inaccurate is that you have conflated a refusal to speak English at home with a refusal to speak English at all. Although many do refuse to speak English. They don't have to. They watch television in their home language, they listen to radio in their home language. They live only among their own people. They only shop at stores in their own neighborhoods.Someone else knows that foreigners generally do not speak English at home. ....
Even you should be able to see how illogical that statement is. In fact, you have been informed that it is factually inaccurate. That you would continue to repeat it despite all this suggests that your prejudice has made you stupid and dishonest (or that your dishonesty and stupidity are the source of your prejudice).
You imagine that you can pontificate about factual accuracy when your pontifications have exactly the same meaning as a particularly smelly fart.
