What's an example of a conservative decision which violates the Constitution? I assume you know a great deal about the Constitution?
The Supreme Court voted 5-4 a couple of years ago that the Boy Scouts of America can't be forced to make homosexuals scout leaders. The 4 conservatives all were in the majority side. The four liberals were in the minority. The Boy Scouts won because the swing vote, O'Connor voted with them. So I take it you think that they should have been compelled to make homosexuals Scout Leaders, since this wasn't an economic issue. If dingbats like you had their way it would have gone the other way, since the conservatives who were all appointed by Republican Presidents wouldn't have been there.
Take your pick of any decision relating to the War On Drugs,for starters. Or any of their many decisions supporting the never ratified and unconstitutional federal income tax. There are many more but those are a decent sampling. Remember that with conservatives in charge instead of liberals you will lose your freedom slightly more slowly; that's the only difference.
I guess I haven't been clear enough about Libertarianism or maybe you're just too used to the Republicans making you choose between economic OR personal freedom. Let me spell it out as clearly as I can: The Libertarian Party is the ONLY party that defends all of your freedom, all of the time. That means economic AND personal freedom. No excuses, no compromises. So our Supreme Court judges will allow the Scouts (and everyone else) to decide who gets to be leaders in their organization. Unlike the Republicans, Democrats and every other party, we don't allow ANYONE to use government power against you or your organization.
Then, review the numerous assaults on the Fourth Amendment given to us by conservative judges.
