They are non-libertarian. That is to say that libertarians support maximization of liberty (essentially the right of an individual to participate in activity undesired by the group or refuse participation in activity desired by the group).
Libertarians generally oppose social regulation and market regulation.
Conservatives generally support social regulation but not market regulation; believing it is a proper role of government to induce/enforce moral behavior but believing market forces to be intrinsic (i.e. all modification will have unintended market consequences/ tradeoffs) and that regulation often acts as a drag on economic growth; they believe the trade-off is usually net-negative.
Liberals generally support market regulation and oppose social regulation; they tend to moral relativism (morality is defined by social groups and is fluid- rather than a fixed concept or a deity) and tend to believe the marketplace contains some intrinsic unfairness and harmful tendencies (in addition to the good it provides [as most liberals believe]) that can be mitigated by regulation and that the trade-off of regulations is usually net-positive.
- Why do many on the Right accuse people who kneel for the flag as being disrespectful of the military, when it's a symbol of respect for fallen soldiers?
- Do you think democracy is more viable when there is a direct democracy or representative democracy?
- What is the libertarian answer to the powerful using their power as leverage to obtain more power over the weaker members of society?
- What are some major differences between libertarians and anarchists?
- Why does the left tend to not support raising the retirement age?
In recent years “deregulation” has been a buzzword of conservatives, but this is fairly generationally specific. In the near term past we might reasonably conclude however that “regulations” in general refer to a more liberal tilt.
