“Europeans have not always treated other cultures as they would like other cultures to treat them.”
Cultures are not morally equivalent. Non-western cultures are usually intellectually and morally inferior. Westerners should not, for example, treat Mohammedan culture as we would have it treat Western culture. Mohammedans need to follow our rules. But, we have no moral obligation to follow, respect, or refrain from eliminating (when convenient for us) such colorful Mohammedan cultural practices as “honor” killing, female circumcision, the murder of non-Mohammedans, etc.
On the intellectual side, would you like to buy a cellphone designed in Upper Volta? Oh...they don’t design much of anything in Upper Volta, let alone cellphones.
The Japanese, Koreans, and a few other countries have “cultures” worthy of respect, but most of the “cultures” in the 192 or so countries in the world should disappear for the good of their own people and the rest of the world.
You’ve chosen to interpret what I said other than as I intended it. Reciprocity and the golden rule do not require tolerating or acquiescing to evil.
