He's a joke, and while he may be sincere, he is an embarrassment to the movement.
People I know who like Adam Kokesh:
-DMT addicts
-alien communicators (see above)
-we've never been to the moon
-Acapulco is a safe, libertarian utopia
-Trump works for Hillary
-ultra poor
-ultra dumb (with all the answers)
One Kokesh supporter I know, a self-avowed libertarian/AnCap, after learning that his neighbor had died, trespassed into his neighbor's shed and stole his tools. A clear (and sick) violation of NAP and property rights, he had no shame.
