You must have grown up with different ideas about conservatism than did I. From most of the reading I have done, and for most conservatives of which I have known, judicial activism was always seen as an abuse of power.
Abortion was a big example, and I know of no conservatives that believe this was a correct legal decision.
The claim that anyone with power decides what is right is one which I absolutely reject. They may decide what will happen, but this only means they have power, it doesn't make them right.
Never said makes it right. Only that is the law. That is fact.
