There was even a whole site called “chavscum” where people would take/upload photos of random poor people without their consent and mock them in the comments

Oh, that’s bad.

When i was in secondary school rich priviliged kids would pretend to be chavs/gangsters for some reason. Many have said the same thing back on reddit.

I agree with other comments that chavs aren’t specifically poor people but rather “criminally inclined” people, notoriously antisocial people. Nontheless some people do just extrapolate their chav hate to hatred of the poor.

It is literally like the British people do not see poor people as human.

I would argue that this is impossible. You see, most british people are “poor” in terms of their disposable income - wages and salaries are notoriously low in this country - so if you don’t dress and act like a chav there’s not really anything distinguishing you from a rich person.
