Thanks for saying what needs to be said. My impression as well is that they just mind their own business and they do not want to be integrated, but merely prefer to coexist in a parasitic form and tied to their own community more than anything else. They have their own culture and traditions which they vigorously isolate from whatever place they live in. Framing the issue as just racism and discrimination does not capture the point at all even though they definitely exist in both sides. We are talking about a community of people that appears in Europe in the 9th century and they keep their cultural identity ever since and the rest of us are scratching our heads trying to understand why.
