An excerpt of Moshe Feiglin’s answer to this question:
Zehut’s goal is not to play the familiar game of the Right, which always leads to more retreats… My goal has remained to create a leadership alternative with a completely different plan of action… The Right is incapable of stating what it wants. All it can say is what it does not want. With that, you cannot go to the public and offer it an alternative.
Allow me to sharpen the answer Feiglin gave as I understand it:
The main problem of semi-libertarians with the ostensible “Right” is their willingness to use Big Government as a means to reach their ends, as opposed to shrinking the state so it cannot be used against anyone.
