The difference here is that early US flags were not created to establish slavery, or continue its practice. The confederate flag and the flag or Texas were flags of nations who were founded specifically to perpetuate slavery.
What in the world are you talking about?
The original USA was a nation that incorporated slavery as a significant component of its economy and law.
So was the CSA.
If you want to try to tell me that the Civil War was a war over the issue of slavery in the South, you're going to have to take it elsewhere. Obviously, it was not, since (a) the key issue under debate at the time was the expansion of slavery into the West, (b) the North had made no moves against slavery in the South at the time of the war, and continued with that pattern for quite some time after the war began, and (c) the Emancipation Proclamation caused widespread civil unrest and military defection in the North.
The issue of ending slavery in the South was a late-comer to the game. (Yes, there were abolitionists, North and South, but they lacked traction.)
So both the early US flags and the various Confederate flags are symbols of nations that sanctioned slavery. Neither nation was "created to establish slavery, or continue its practice" nor was either nation opposed to slavery
per se (at least at the outset) and both of them made conscious collective decisions to affirm it.
The difference is simply that no aspect of slavery was an issue in the rift between Britain and the American colonies.
From your statements it seems I'm expected to believe that the Founding Fathers' support of slavery was somehow less eggregious because no one challenged them to a war over the issue of its expansion.
Had slavery been an issue in the Revolutionary War, do you really think the colonies would have supported emancipation?
I mean, before the Proclamation, was the Union flag a symbol of hate because the Union sanctioned slavery in the South and then failed to make such a proclamation at the outbreak of the war -- that is, when the North was insisting that the war was over the issue of union and secession and not slavery? And then suddenly it stopped being such a symbol when the EP was issued?
If so, then the St. Andrew's Cross stopped being a symbol of hate when Lee signed the surrender and slavery ended. If you're going to insist that changes on the ground alter the significance of the flag, then that's where it leads.
And the thing is, the St. Andrew's cross is more widespread now than it was then. It has long been a symbol of the present South, of today's South.
And there is no other clear symbol for Southern identity. A Molly Hatchet poster won't cut it. The St. Andrew's cross is what we're left with. And folks who are raised first and foremost (as I was) to see it as a symbol of the South, and only later learn about its history and the Civil War, it remains a symbol of today's South, regardless of what it used to stand for, just as the Stars and Bars stands for America today, regardless of what kind of government or policies it used to represent, whether that be slavery or killing Indians or invading Mexico in order to get more land.
Granted, it's been widely used for overtly racist purposes, everyone knows that.
But for lots of folks, that's kind of like a mainstream Islamic view of Muslim terrorists citing the Koran -- just because they abuse it doesn't mean they own it.
