Don't those left-wing nutjobs believe in their own judicial activisim
The types we are dealing with do not take positions based on overarching principle. Instead they take individual positions they were convinced to by their peers or superiors regardless of context. Thus, you will see conflicting positions that amount to obvious hypocrisy.
Two recent examples:
A Republican speaking of "Freedom of religion" while supporting a law allowing vouchers to be used for religious schools, then backpedaling quickly when she realizes that Muslims schools will get money too. She's not for the principle of freedom of religion, she just wants to promote her own religion.
A liberal satying that the Founders were talking about muskets in the 2nd Amendment, and couldn't have envisioned modern firearms, therefore the 2nd Amendment doesn't cover modern firearms. They of course have no problem exercising their 1st Amendment right to say this over the Internet, television and radio. This person doesn't really believe that rights should be restricted to the technology of the time, he just wants to ban guns.
