Varieties of criticism
Conservative criticism has nothing much to do with "left-wing" or "right-wing", because left-wing people are often very conservative, in the defined sense, while right-wing people can also be very radical, in the defined sense. The difference between "radical" and "conservative" has more to do with the belief in whether "a change to something genuinely new" is really possible and necessary. Radicals typically believe strongly that such change is highly desirable and necessary, and that it can be achieved. Their criticism is that there is "not enough" change. Conservative critics, by contrast, are very skeptical about any such change, because they feel the change is really "just another form" of something that already exists.
The Reactionary Mind
Alex Gourevitch praised Robin for attempting to develop a comprehensive understanding of conservatism and for trying to examine conservative ideas rather than dismissing them outright. He also praised Robin for examining how conservatism can learn from the political left. However, Goutrevitch also criticsed Robin, arguing that Robin dismissed important differences between different branches of conservatism, as well as similarities between the political left and right, which Gourevitch felt hurt Robin's thesis. He also questioned if conservatives actually intended to defend hierarchies or if these are simply a consequence of conservative ideals, observing examples such as libertarianism, which often results in hierarchies yet libertarians regard themselves as defending freedom and opposing domination while viewing leftists as introducing their own forms of domination.
