Did you want a reply, or the catharsis of getting downvoted from "stupid" users who like rap?

I want an argument about how often I am seeing people being offended by having their preferences criticized. I can take somebody disagreeing with me (except on this issue, of course :) ), and civil society relies on criticism, and people accepting criticism. Berating people because they are dismissive of things they don't like is a path that lies madness. Feedback should not be purely positive, truncating the negative, because then effects that are polarizing or simply have costly disadvantages outcompete effects that do are more mildly positive, but without (or fewer) drawbacks.

Saying that rap is not music may be criticism. But it is certainly ignorant and unconstructive criticism. It is criticism in the same sense that "your mom" jokes are.

Right, there's disagreement to teach or learn about another's opinion, but you're engaged in something more indulgent.

I don't believe you're interested in the merits of civil discourse, no, you just enjoy the declaration of your opinion.

"Feedback should not be purely positive," right, it should at least be constructive.

...but it's not a post about music preferences, it's a post about software usability.

Software usability of what? Music preferences software.

I get mine muddled, is this a fallacy of composition or texas sharpshooter?

I see what you did there
