Anyone who's ever worked knows that the most effective team is one with multiple strengths, we need people who are good at mathematics/technical skills, people with social skills, people with decision-making skills etc. All cultures have something for others to learn from, if nothing else by bad example. On the other hand, if someone thinks diversity is only positive in all cases, they're clearly an idiot.
Then there are those who oppose diversity, and this is pretty much all borne of fear. Fear of strangers, of people that look different and seem scary, of losing your job/spouse/economical stature, of violence, crime and terrorism. They see diversity, immigration and change overall as threats, and if you're only using your lizard brain, fear is by far the strongest emotion and motivator.
Diversity can be a big asset, but it requires an environment open to integration, giving the immigrants possibilities to act as productive members of society and feel welcome. If immigrants feel accepted, they are far more likely to adopt the new culture, aka integrate. Prejudices are probably the biggest reason for failures in integration.
