What’s had a certain level of success in the UK is similar to what you’ve suggested. Mark Collett’s Patriotic Alternative fell under intense attack from the establishment government, media, and left wing terrorists through measures such as de-platforminf, cancelled bank accounts, and physical assaults.

What they did was build an underground network where hundreds of people meet up in real life regularly. Not only is that network a cultural one, it’s now an economic one. People buy goods from each other, and financially support one another when one of them falls victim to de-platforming.

In my country, while we don’t call ourselves ‘alt-right’, groups of racially conscious people aware of the demographic threat have banded together. Many of these people have their own businesses and skills, and whenever one of us needs work, we often hire from within the community. We help each other out in our businesses and careers, and through this economic in-group preference, we have an edge over other businesses.

Does any of this allow for revolution? Of course, not directly. However, with the money and social status we accrue, these groups gain the ability to fund and greatly assist nationalist movements.

Essentially, we’re doing what the jews do with organizations such as ADL, and Hope not Hate.

A group of highly ethnocentric people with massive economic power wishes to crush us, and in order to survive, we have to play the same game.
