Whether it is for the preservation of Western civilization or the White race itself, I think it's clear that nationalism as a political movement isn't the answer.
Globalists control culture, media, education, the Government and even the public's perception of Morality itself. At the same time, the public is extremely apathetic towards politics and has deactivated it's instinct of self-preservation.
When it comes to society, people in their 40s and older rarely change their political convictions or adopt new ones, while the youth are extremely "globalistic" and Multi-racial which further renders nationalism as a failure.
In view of reality, it seems that what you people are doing is nothing but a waste of time. You have already failed, before even starting.
