Well I can agree with this statement about 90% of the time in the current environment. There is a sub-set of people who the South who lineage is Confederate veterans who "support the Confederacy". But I will note they are generally not the ones out there defending monuments or flying the confederate flag -- they are more focused on cemetery and battlefield preservation in the modern era.
Wow Grand wizard Snark is all into posting rebel flags today. He has files and files of confederate flag pictures on his hard drives As any rebel would do what he does and posts the flag under the guise of "anti trump"
You might want to familiarize yourself with something called google for Trump/Confederate flag pics moron.They can be found there faster than a hard drive.
