I'm not a white nationalist, or even white really, but can you see what is happening?
Familiarize yourself with the notion of radicalisation.
It's a process one undergoes that causes resentment and activity against the state or in the furtherance of a cause. In contemporary times we are exposed to terms such as "Islamic radicals" but a better term would be "Islamic fundamentalism", These people are true believers in the Islamic faith and actively try and fulfil their Muslim duty to make the world hospitable for the rule of some Holy Man called the 12th Imam or the Madhi.
Traditionally, radicals and radicalisation was associated with left wing activism, feminism, Marxism, green movements, gender equality, gay rights, workers rights, peace, anti war etc. Let's do a quick study of 1950-1980 and see the threats these ideas posed to the government.
Left wing - liberal/socialist when the government is conservative and free market. Undermines public trust in the government.
Feminism - aims to break down enforced social roles for the genders, removing an invisible chain around the necks of the oppressed masses. Threatens the government as it makes people less easy to control.
Marxism - encourages sharing and that your life is your own. Threat to the government as our society is not like this, and erodes social institutions. Government demands it be confused with Soviet military, the ideas are so dangerous.
Green movements - Encourages responsibility and respect as well as collective individual action. This is clearly a threat to the government - people thinking about social responsibility and taking action.
Gender equality - feminism
Gay rights - similar to femenism
Workers rights - encourages you to see ourself as a special snowflake instead of under the yoke of a boss where you should be grateful for a job. This is dangerous for the government. The government is scared of "uppity niggers".
Peace movements - the government generates much trust from the public by creating boogey men and encourages you to feel a sense of safety in community by saluting the flag, hating Cubans, joining the military and baking cookies for the police. Encouraging pacifism will cause people to turn against these ideas, and considering our government gets power from the barrel of a gun, this is a huge threat to the government.
Anti war - similar to peace movements, but with more awareness of the individual and how they go and fight, get mentally broken, might lose legs, might die etc, to come home and work 9-5 in a factory and nothing more, meanwhile a select few are making billions off their blood shed and now their hard work and sweat. This individual self respect threatens the government, obviously.
Now back to radicalisation.
Most people don't have time to come up with these ideas by themselves. They are raised in a system and this is all they know. They are preoccupied with work, school and MTV. Radicalisation occurs when someone turns against the government and works to destroy it.
All the types of activism previously mentioned have come about due to radicalisation, or opposition to the government. It could have been due to something like wrongful arrest, having too much state interference in their lives, and generally a feeling of persistent hopelessness. From the emergence of these feelings resistance arises. People who no longer want to be friends with the government start looking for another place to get their sense of community. They find it in the "enemy". Everything the government says is bad becomes appealing because they are against the government.
Soon they discover the "bad guys" have ideas that actually would make the world a better place. And they go on a karmic crusade trying to improve the world and bring us out of the dark ages. They dedicate their lives to this.
Now, back to everything else:
There is a state encouraged level of apathy and conformity we all are supposed to have. When there is a problem, there is a national debate we choose a side in and it all gets fixed. We feel a part of this process, we are not.
Radicals are aware of the brainwashing we are under. They know we do not act.
They are also still trying to destroy society and rebuild it.
Part of this is to welcome other cultures and values, to encourage immigrants to keep their values when they come here to dilute our culture. At the same time, traditional western values are denigrated and opposed at every opportunity.
This is where the white nationalist movement comes from. It is a strong supporter of the culture required to maintain government influence and power. They are violently confronting political dissidents. They are the secret police. They are state sponsored. They use Nazi symbology and anti Israeli rhetoric to afford themselves plausible deniabilty. They are terrorists. The government is using terrorism to attempt to stay in power by scaring the radicals away from activism.
The radicals are going to win. They have reached a level where their ideas are commonly known and accepted. It has reached a critical mass. And the secret police are using terrorism.
