It's more like 160k Syrians in the Netherlands. Meanwhile groups like Moroccans, Surinamese, those from the Antilles and Turks are somewhere between 300-500k all the while majority of them being in the Netherlands for decades. So the Syrian population is definitely going to become one of the biggest in the next years.
Like you already said it's funny seeing these racist middle Easterns, north africans and south Asians against black people when infact black Caribbeans are usually the most integrated, assimilated group in the UK, Netherlands and France. There are more biracials than black ones because of the extremely high interraciale rates from both black Caribbean men and women.
I would say that they are very much more integrated than other Europeans from the eastern and southern part, for obvious reasons like colonization and thus speaking the same language, religion, sharing some blood (for those whose ancestors were raped by brits), traditions, customs, some food etc.
These cadaans are racist against everyone but nobody would deny that they would rather have blacks in their countries than them. Black Africans are literally minding our business, focusing on our education/family/life. It's really only in France and Italy i see some black Africans being involved in crimes in high rates but even then it pales compared to the official statistics on north africans and people like Pakistanis/Afghans (sex crimes).
