"legitimate complaints about africans, chinese, jamaicans or portugese in the way we sadly do about roma and travellers."
I get what you're saying, but I don't agree that's a fair comparison.
africans, chinese, jamaicans or portugese do not share a common ethos or set of beliefs amongst themselves. Of course all travellers don't agree 100% on all topics, but there is a clearly identifiable "thread" between their group stance on e.g. underage sex, the role of women, adherence to planning laws, whatever - the same cannot be said for the population of countries in general.
That's why I relate my own comparisons to religious groups. That's a much fairer comparison.
I have thought of 1 national group which I may feel appropriate to compare against and make similar comments about: the Saudis. Women are treated as 2nd class citizens there* and it's a general attitude across the population, from what I can tell. With exceptions, of course, individuals are individuals and the usual comments about it not being a mindless group all thinking the same things applies. Can you imagine if, say, people of african origine were treated the way women are treated in Saudi Arabia? No driving, permission from male relatives to travel, whatever. There would be an international outcry. Modern day slavery.
Interesting anecdote from my boss that I heard last month: he's sort of on the PR / face front of the organisation I currently work for, and used to work in another company which had a lot of middle eastern ties. His partner (business partner) at the time was the woman who co-founded the company with him. In 99% of the middle eastern (ok, it was pretty much Saudi Arabian) meetings they held, they assumed she was his secretary/PA and kept her out of the meetings. Cruellest of all, the first few times he pointed out that she was co-owner, she was still kept out of the meetings, and spent most of them on a laptop in hotel lobbies. Can you imagine if this was done to a male co-owner simply because he was black, chinese, welsh, whatever?
