Besides, it's deeply disturbing that you advocate naturalizing foreigners only for the purpose of winning elections for center-left parties. If they have to rely solely on this to win, they are politically bankrupt because it shows that they have no solutions to actual problems...
That's not the only reason I support it. I also think taking in more immigrants is morally right as well as beneficial both economically and culturally. In short, there are only advantages. The electoral marginalization of racists is only a welcome side-effect.
Why should it be morally right to crowd out a people in their own homeland?
The idea that people are being "crowded out of their homeland" is nonsense on so many levels.
