I know nothing of 14/88 or Stormfront other than what's posted in this thread, so yeah I'd stay away from that.
I was born in the North, so I'm not a southerner, but without the other two flags, I'd have no problem letting my kids be friends with a family who flies the Confederate flag. Not my cup of tea, but it is definitely not inherently racist. The symbol has been hijacked in recent years to mean something that it was not originally intended and is now being used as a lightning rod to divide people.
I am a southerner, & I agree about the Confederate flag. It is not inherently racist, but I still don't go around displaying it or waving it around because I know what the connotations can be. And I don't want anything I do to cause anyone any additional hurt.
An entire region of the country can be wrong. The Civil War and the Confederate flag were all about slavery. Displaying it is a tribute to that. So are those statues. And those streets and schools named after slave traders.
My point is: you can be a racist AND hate. But it's not essential. You can even say something nice and be a racist. Like "those colored folks sure can dance." See, a perfectly good compliment. isn't it?
I wasn't going to comment, but...
The Civil War and the Confederate Flag were not all about slavery. Sure, slavery was one of the main issues, but not the only one. So, if you're going to use the Civil War in your argument, be familiar w/ all the history - not just what suits your argument. Many in the South were fighting not for slavery (& many didn't even have slaves) but were fighting for states' rights. My ancestor, who picked his own cotton w/o any slaves on a very poor dirt farm in northern Alabama, fought for his home state - not because he was trying to keep slaves. There were many other multi-faceted issues to the War as well. And, coincidentally, BOTH the North AND the South profited from slave labor - so the North is not the blameless heroes that many make them out to be. It was a sad, tragic time in our country's history, no matter what side of the Mason-Dixon line you fell on. So, it's not really an entire region of the country that was wrong; in actuality, the entire country was wrong when it came to slaves.
And your determination that an entire region of the country is racist because of a flag & some statues is both sad & misguided. (And I know you didn't come right out & say that, but it's implied in the context of what you did say.)
Displaying the Confederate Flag is not necessarily a tribute to the Civil War & slavery - it definitely can be. But it isn't always.
I do agree w/ your 2nd paragraph.
Regarding the OP, like others have said, the Confederate Flag alone wouldn't necessarily make me suspicious but the Confederate Flag along w/ the 2 other items would make me run. I wouldn't want my child around the family at all.
I am surprised that the OP was able to just take pictures in someone else's garage, & I have to admit, I'm a little suspicious of the whole story.
(And I had to google because I had NO IDEA what either meant.)
