Multiculturalism isn't the cause of the population crisis or immigration so whinging about it achieves nothing. If anything it distracts from the real issue. I also think people's complaints about multiculturalism are hugely overblown, and that it can be made to work quite well. My city has about 30% of its population born overseas. We don't have any major issues caused by multiculturalism.
What is "emotionally reasoned" and can you give me an example of me doing this?
