I think he is talking about right and wrong with respect to matters either of taste, or where there is no evidence to suggest something is right or wrong.
Well, when there’s no evidence, then anyone could be right or wrong. It is the only area where opinion is the only thing that counts, and where, if you express your opinion cleverly or forecfully enough, you might persuade others to change their minds. If you are successful at getting people to follow your opinion, that can be such a rush! That’s why people try so hard.
As to matters of taste, some people don’t understand that degustibus non disputatem est. Again, if I could show you that eggplant really is good, when you think it totally sucks, then I feel this sense of power. I mean, man am I good!
I think it’s like that on fluther. It’s not so overt; we don’t usually argue right and wrong, but it’s still there: the possibility that we can persuade people to see things differently than they used to. Like now. I’m hoping you’ll find my explanation persuasive, and give me lots of lurve! Especially you new people who haven’t run up against your limit for giving me lurve.
Sigh. Am I a shameless huckster or what!
