In the end I understand the offense of those who celebrate a different side of the war.
That's where people have it all wrong. Nobody "celebrates" a war they lost.
I ought to have used a different word (commemerate?), but I disagree. Many people have undertaken many worthwhile endeavors & failed. Failure doesn't negate the fact that One has tried to do the right thing, nor necessitate a less than celebratory response.
That flag represents the opposition of an oppressive government, therefor it must be silenced.
I absolutely agree that this is the ultimate issue here.
