Relativists cannot base their worldview on relativism when it suits them, and then turn to asking someone whether or not an opposing worldview or something they posit is abolutely true.
They either believe in absolutes (moral, cultural) or they don’t.
If they don’t believe in moral, cultural absolutes, how then can they say that something is, or ask if something is absolutely right or wrong? They are asking a question that they do not intend to agree with when answered.
Why?
To them it is all relative to POV.
I believe in striving towards what one may believe to be an absolute, but I really can’t say I believe moral absolutes exist. I don’t know any relativists, so I can only speak for myself...and I may be wrong.
