No, in this case I disagree. You could say the same thing, word for word, about any real-world ideology and it would be equally true. If you think I'm wrong about that, I would like a concrete example.

(Maybe you think I'm trying to say that all ideologies are equally valid, but I'm not. I'm just pointing out that that particular comment is so reasonable-sounding and hard to argue with precisely because it doesn't actually say anything of substance.)

"Sure, but not everyone enjoys spending their time engaging with vegan rhetoric. There are plenty of places outside of Twitter where you can actually choose whether or not to have a discussion."

By this logic, Twitter should ban pretty much any ideology.
