Trees are known by their fruits, a rotten tree cannot bear good fruit. That a person claims to be something or someone that they are not is nothing new, so it should not be surprising that this happens. Likewise, there will be those who claim to be Bitcoiners and behave like Shitcoiners. The healthiest thing, I have learned the hard way at times, is to doubt, always doubt. Observe and then act, and even after having doubted and waited, continue to doubt.
A libertarian, the concepts are different and even attempts are made to place oneself in political currents of the Left or Right.
"Libertarians advocate the expansion of individual autonomy and political freedom, emphasizing the principles of equality before the law and the protection of civil rights, including the rights to freedom of association, freedom of expression, freedom of thought and freedom of choice." With this concept as a basis, anyone who tries to curtail the freedom of another is no longer a libertarian.
