You sir are incorrect. The acknowledgement of relative subjectivism does not necessarily inhibits one from creating their own subjective philosophical perspective.
I would think accepting subjectivism necessarily means that one also acknowledges their own subjectivity. Hence accepting that you already have, much less need to create, a unique, subjective, 'philosophical' perspective. To some extent, I agree with Kilgore's post. It is much easier to criticise, to avoid, to relate without any definite argument rather than ploughing your own way through life, leaving behind your own unique wake. On the other hand, I feel that the concepts of nihilism and relativity are valuable because they teach the human about meaning, meaningless and continuity. They are 'big picture' philosophies that come in handy for one side of the idealistic spectrum but not very valuable if, say, you want to have a serious career. I feel as if nihilism especially eliminates passion. In that sense, you are too lazy to pursue something that might have meaning for you, because as a nihilist it should have no meaning.
Two of my favorite movie lines ever (from the Big Lebowski): Bunny: "Oh he doesn't care. He's a nihilist." The Dude: "Hmmm, that must be exhausting." followed shortly thereafter by... Bunny: "I'll suck your dick for a thousand dollars. **** can't watch though, or he has to pay a hundred. The Dude: "I'm just gonna go find a cash machine..."
