So you argue that humanities are like art, cooking, literature, sexual preferences: a matter of personal taste, which I supposedly lack. The general consensus about matters of taste is that it is pointless to argue about those. And that matters of taste are an indulgence, important only to fans of that particular variety.
Which means that humanities cannot be important to mankind as a whole, because most won't appreciate them, as they are a matter of taste. And they are as arbitrary as other matters of taste, lacking the universality that is necessary for usefulness. Good riddance!
Ah. So you determine I'm not in the in-group for the magic circle that is humanities, so I can never appreciate or evaluate them. And you place any evaluation entirely in the subjective realm, such that no objectivity is possible anyways.
So it's not just a matter of taste, humanities are a cult.
You are stating that a specific segment of human experience and knowledge is a cult, without a sensible argument, and as displaying a very astute contempt and seeming lack of experience towards this segment. With an absolutist stance. And then, ask people to prove you wrong. What do you expect?
