I personally didn't go around calling rebels in the game 'sister f*****s' or 'cousin f*****s', but I hardly think that's on the same level as calling someone a 'n*****lover' - I agree that they're similar inasmuch as trolls and others think they can get away with such behavior in games, which sucks. Incest and racism are obviously both wrong, but incest doesn't denigrate a whole population of people - and it's not a divisive issue that's prominent in society today in the US.
I may be naive on a few fronts, I don't dispute that - and I'm always up for learning - but for me and many others it's hard to see the CSA battle flag and monuments to CSA generals being displayed in public as anything other than honoring a legacy of racism. Slavery was one of the cornerstones of the CSA, and there's a reason it's illegal for anyone to fly that flag on our military installations today.
As far as I know, Lee struggled intensely with his decision of wether to lead the US forces or to lead his fellow Virginians, and he was an honorable man to the end. That still doesn't make him a national hero though, so I think everything should be in museums that explain as much historical context as they can.
Here's a good article with historical context if anyone is interested
