Nationalism: the limits of what is acceptable
Navalny never renounced his right-wing views. Everyone who was ever interested in him, both the Narod movement and other. It just didn't work for a while. And now it's not that for him personally, this was updated - it’s just that the topic became more popular, and he could not pass by. That is, he behaves in this sense completely natural to you. In "Russian Marches" he used to participated, except that he had not been a member of the organizing committee before.
