I think the primitives biggest problem with rights is the unwritten bill of responsibility. Once the government comes in and tells society what it can and cannot do, the need to behave responsibly vanishes.
Take for example, Phelps.
He believes the government has given him the right to free speech, and therefore he ignores any responsibility involved with it. -Which is why he and his clan have no problem disrupting funerals.
also..
Many people believe they have the right to government granted 'entitlements' and feel no need to have the responsibility to get off government assistance programs as soon as possible.
And of course, the 'right to government healthcare' - where people will start going to the E.R. for splinters and bruises, and many will stop behaving responsibly because the government will fix them up for free. Examples - Free bariatric surgery, free anti-smoking medication, free abortions, free drug/alcohol addiction treatments, mental health care, gyms, etc. etc. etc.
