Migrants are people first, not "problems". They have rights, they have value, they have skills. As in any population, some will be an issue for society, nad you'll need to deal with that. But that has little to nothing to do with them being migrants.
And the whole "anti-democracy propaganda", as you called it, is mixed up in there too: The far right wants to take away human rights. They'll start with the weakest link, which may be migrants or disabled people or ..., and work their way up.
