No, pluralism as you define it is value neutral, just like relativism. It is dangerous and insidious because it can be used to over turn our legal system, which is not value neutral.
Our legal system is based on Judeo-Christian law and Sharia Law is in no way equal. To consider any other culture or religion as equal to US culture or the Judeo-Christian value system is insidious and dangerous.
So do you want our laws based on Jewish law or Christian law?
They are not identical.
