On certain issue, like the degree of socialism within the government, that's ok. But on freedom issues, it's a different story.
No, it's not a different story. This is the idea of Federalism--South Carolina isn't enslaving anyone and they haven't put up guards at the border to keep people from leaving.
So tell me again, how is their freedom affected? You want to buy a dildo? Drive to North Carolina--they can start selling them at "On the Border" with those tacky concrete lawn decorations.
