There is nothing to "give up". We are not on a ideology bazaar.
The alt right should give up propaganda including fake news, being anti-democratic, xenophobic and hateful for everything that doesnt share their opinion.
If the desinformation movement is going to start to use democratic means of politics, they are surely going to convince people. But as far as i see it now, they will lose every single vote from the protesters once they ever have to become establishment, as the protest voters cant be adressed by right ideas, but only by ideology that adresses the neo liberalism consequences.
Trump shows where this ends. In making everything even more worse.
