Therefore, there are many different truths. If we can't know about something, there's no reason to believe in it. We can't know about objective reality. For, whatever we perceive is only a perception or 'representation' in our own minds, and so is not objective reality. So there is no reason to believe in an objective reality.

Therefore, we should be relativists. Relativism either excludes some alternative view, or it does not. If relativism excludes an alternative view, then it is contradictory. If relativism does not exclude any alternative, then it is meaningless. They publish irrational articles for propaganda purposes.
