2nd Amendment. In the DC handgun case last year. It stood for 32 years. A ban on owning a handgun or an operable rifle or shotgun in your home was illegal. It was a 5-4 decision. Really? No way that shouldn't have been a 9-0 decision. One more liberal judge and it would still be against the law to own and posses a firearm in your home if you happen to live in DC. Apparently the 4 didn't think it important enough to be able to defend your home, unless you had a knife or hatchet of course.
I think that you're mistaking the opinion that this portion of the amendment:
"A well regulated Militia, being necessary to the security of a free State..."
puts a very specific limitation on the right to keep and bear arms for a hatred (or contempt) of the Constitution itself.
If that phrase had no limiting effect, then why wasn't the 2nd Amendment just written to read:
"The right of the people to keep and bear Arms, shall not be infringed."?
It is possible for reasonable people to disagree on the meaning of the text of a document without one of those people being contemptuous of the document or its contents.
