Different races and ethnic groups have different behaviours that are well correllated with them.

Niggers have a disproportional violent crime rate. Indians in the West show nepotism in who they choose to work with. Poor Asian and Latino migrants in the West are generally less considerate of others, louder and more rowdy compared to White folks in the same region.

So, yes. It has a bearing on their character. Whether the reasons are socialisation or biological is another question.

Also, just like ethnic groups outside the West are allowed to take steps to defend their cultural behaviours and remain a majority in their countries, I am also justified in calling out excessive migration in the West by people that appear to put zero effort into assimilating.

E.g. Indians won't accomodate you as a worker in India if you can't speak Hindi. But they work in the English-speaking West with a very poor understanding of English and yet, expect accomodations on jobs
