First, the claim of philosophical relativism is itself an absolute truth claim. And as such, it is self-defeating because for this statement to be true, there must be at least one absolute truth, which means that the statement is false. This is a pernicious hypocrisy. It condemns absolute religious truth claims as bigoted, but it is the new dogma, and you will be shamed, scorned and mocked unless you accept it. So much for the background of religious relativism.
Religious relativism is intellectually untenable.
This is because it violates the law of non-contradiction. It is inconsistent with how we form conclusions on other important truth issues. We don't operate like this in other important areas of life that deal with truth claims. Both are true. Both answers are fine with me.
