No Jim.
I think it unacceptable to use labelling and name calling in place of argument.
Your post today does not challenge any opinion in any way except to say that it is racist.

That is the only argument you have.

Suppose the cultural explanation were true.
Is it still racist?
You are not sure yourself it is not true.
How can non racist people propose a racist opinion?

Try to discuss this issue without using the word "racist" Jim.
