It’s a symbol that says “Are you offended by this flag? TOO BAD FOR YOU!”
The flag doesn’t OFFEND me!! I grew up in the north (in Connecticut) and I moved about 13 miles from where the flag is FLYING (on private PROPERTY). If I was alive in the 1860s, I would have supported the STATE RIGHTS of the CSA. Sorry, they knew Washington DC was becoming power hungry, and they wanted to fight it. The CSA was right — and I know that we want STATE RIGHTS — not FEDERAL RIGHTS!!
