anonymous question

I think that if you meant the literal meaning of the expression “jumping on heads,” the answer would be banal: this is violence that is not a response to a violation of the NAP, therefore the person who jumped on the head has no right to remain unpunished, and their behavior certainly does not correspond to libertarian principles at this moment.

Also, I think it’s clear that you aren’t actually asking whether a person can call themselves something. A person can call themselves whatever they want; that’s what freedom of speech is for.

So I will answer the question in the following formulation:

Should one trust a person’s claim that they are a libertarian if it is known that they exhibit non-violent aggression toward those who hold (also) other ideologies, but who do not impose them on anyone and do not violate the NAP?

Alas, however tempting it may be to deny any asshole the proud title of libertarian, it must be admitted: a libertarian can be an asshole. Due to personal dislike, they may non-violently cause you any unpleasant experiences, and even provoke you into violence, but they are within their rights, and this is a completely conventional libertarian way of behaving in a conflict. Applying retaliatory non-violent sanctions to them—be my guest. Spitting in their face—that’s bordering on a foul. Lunging with a knife—be prepared for the fact that both they and everyone present will be able to unpunishedly apply any violence to you to prevent your actions.

And as for which ideology you peacefully adhere to—it doesn’t matter at all—even if it’s socialist.
