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.
Conservatism
National conservatism is heavily oriented towards the traditional family and social stability as well as in favour of limiting immigration. As such, national conservatives can be distinguished from economic conservatives, for whom free market economic policies, deregulation and fiscal conservatism are the main priorities. Some commentators have identified a growing gap between national and economic conservatism: "[M]ost parties of the Right [today] are run by economic conservatives who, in varying degrees, have marginalized social, cultural, and national conservatives". National conservatism is also related to traditionalist conservatism.
