Of course, it is because their ideological views on security and absolutism, when dissected, are exposed as utter folly.
For example, anarchist society will always degenerate into absolutism because there are no intentional institutionalized constraints on the formation of monopolies of armed force.
And we all know that ‘power corrupts, and absolute power corrupts absolutely.’
Moreover, the anarchists on MIses.org forums are not really capitalist – they are more faith-based pacifist. Hence, logic and empirical evidence is discarded and censored by anarchist ideologues if it does not conform to their faith-based belief in the pacifism of anarchist society.
