If you want to be politically successful on behalf of our cause (or any cause), you have to know what works politically. If you don't want to become skilled in the arts of practical politics, you'll end up wasting your time and ruining your reputation while getting nowhere. The fact that a political party has formed to represent the rights and group interests of European Americans should be enough to merit our support.
Furthermore, policies of free association in place of ridiculous "anti-discrimination" laws would work far better than forced integration or segregation. By right, the people should have the freedom to choose with whom they associate. Allowing human beings to behave in a way which reflects our tribal nature leads to far more harmonious societal outcomes, as restricting freedom can only worsen the human condition. By trying to work around our innate tendencies, we make society less happy and less free. As realists, we would enact laws which compliment human nature and would remove laws which attempt to circumvent it.
After only decades of living under "multiculturalism", world leaders have begun to recognize it as a failed social experiment. Instead of ushering in a new age of equality, peace, prosperity, and brotherhood as promised ("diversity is our greatest strength!"), it has created conflict, tension, destroyed education, and has caused the breakup of once cohesive national communities throughout the West (diversity is instead perhaps our greatest weakness). The dismantling of multicultural societies in favor of kinship based societies is but an inherent mechanism of tribal defense and survival. World history proves that balkanization is humanity's natural backlash against multiculturalization. By Nature, people seek not to erase or ignore differences, but acknowledge differences and find comfort in commonality.
We would do well to avoid being associated with the bad feelings caused by a concept like forced segregation. It's actually a good thing that we would never make it illegal for different groups to interact with one another. Naturally, we are attracted to similarity and seek it out whenever we are able. In terms of demography, we don't have to tell whites to stick together; like any other people, we already do it on our own. As always, liberty is the answer to our problems.
To win our people's support we have to be more than a just political party or a civil rights movement. We have to a be the beacon of peace, security, and freedom!
