The constitutional amendment I'm refering to is the "gay marriage" amendment, the Patriot Act is not a constitutional amendment, but I will agree it is scary.
The funny thing about the second amendment is that more and more Repubs are saying they would support more laws. I will give you that the left is far more worrysome in that regard though.
The right may have a more traditional base of personal rights ideology, but they are increasingly for big business, that is NOT good for the personal rights of the average citizen. Witness the increasing use of Eminent Domain for private businesses like Wal-Mart and large developers.
I too worry about political correctness, I feel it is a real issue in this country, and across the world. But it is certainly not something only the left is guilty of. I do think there is a fine line between being Politicaly Incorrect and disregard for anothers feelings. It is our right to express an opinion, but the Golden Rule still applies.
