Your response shows that goyishe kup is used as a perjorative to indicate thinking that is inherently faulty. The use of goyishe in that expression plus your using it to insult people you disagree with shows that you believe it's typical of the goyim to have faulty thinking. To you, people who are not Jewish are inherently inferior in the way they think to people who are Jewish. Your use of goyishe kup in this thread is form of religious bigotry.
