Fair enough. I do have a specific sentiment in mind, though, and it's not the constructive kind, which I very rarely see anymore. I would classify "anti-American sentiment" as sentiment which is against the Western culture that has predominated since the founding of the country.

But it's a slippery slope. If someone love America and wants a revolution to turn it into something historically unrecognizable, does that still make them pro-America? I would say no.
