Not sure what the 'no' is in regard to. That's entirely aligned to my comment.

Or did you think obstinate devotion to opinions and prejudices only manifests in the the group of people you happen to disagree with?

You focused on unwillingness to change one's opinion. That's certainly a definition, but the more common one in use is about prejudice, especially prejudice based on inherent traits like sex or race or sexuality. I'm sure you're aware of that, which is why it's confusing that you're acting as if you're not.

I don't dispute that it's extraordinarily difficult to get people to change political opinions, especially on the fringes. That was never my contention, I made that pretty clear with the example of bigoted communities I chose being white supremacists. Not sure how you could misread that, unless you wanted to.

> It's the inability to accept new viewpoints

No, it's not just that. I don't understand why you're being intentionally obtuse here, other than that the framing helps your viewpoint if you can trick others into accepting it.

Words can have more than one definition. Yours isn't the one I was using, no matter you wish it was otherwise.

Again, since you apparently missed this the first time around, or intentionally ignored it:

> especially : one who regards or treats the members of a group (such as a racial or ethnic group) with hatred and intolerance

"When I use a word," Humpty Dumpty said, in rather a scornful tone, "it means just what I choose it to mean—neither more nor less." "The question is," said Alice, "whether you can make words mean so many different things." "The question is," said Humpty Dumpty, "which is to be master—that's all."
