I would argue that most in the alt-right don't even condemn zionism, for they tend to blindly follow Trump and Qanon and others who push extremely zionist agendas. Many in the alt-right zealously defend zionism. Some do condemn Jews in general, which makes the alt-right look bad to the masses, but when push comes to shove they seem to still always push the zionist agenda of war and hate. I honestly don't see that many in the alt-right who are anti-semetic but rather many more who seem to hate Mexicans and Muslims...

There are in fact many Jews in the alt-right like Laura Loomer who are hardcore Jewish and zionist apologists, so I think it's wrong to say that the alt-right condemns both zionism and Jews in general, for there are only a small minority in the so-called alt-right who do either... The media just likes to focus on the minority who are anti-semetic to fuel the divide between alt-right & progressive-left, and they also like to falsely paint anti-zionists as anti-semetic to smear and discredit them.

The alt-right is just another controlled opposition movement to pull the waking masses back into the two-party system and left/right paradigm, and to keep the illusion going that the real fight is between the left and the right. The author is certainly right, Libertarians should steer clear of making any alliances with the toxic alt-right.
