I think we are mostly on the same page.
The thing is, not everyone even knows what the common white supremacist symbols are. My black friend (also my shooting buddy) is making his own RPG and I am making the character sheet for him and he wanted some of the stat boxes to be a “plus sign in a circle”. And he sends me a picture of the white power cross and says, “Kinda like that.” 0_0
So your point that other than say “MS13” in black letter, most people can’t ID gang tattoos is a valid one. But my point still stands that people kicking out others because they are 99% sure they have gang tats is going to happen more often than kicking out people for white power tats.
While not all white supremacists are violent, too many of them are. So I can’t really disagree with you on that. But I don’t think one can legally deny people on that alone.
Well, you got people punching Nazis. And despite if one thinks they have the moral high ground on the issue, it is still illegal and there will be real world consequences. Even with the BLM and that Oregon stand off, it was mostly bloodless (IIRC they shot one of the Oregon guys.)
While the policies have changed some since the 90s, remember Waco and Ruby Ridge when the gov wants to get violent. Remember that we view the OKC bombing as not a fight against a tyrannical government literally murdering civilians but as the worst domestic terrorist event in history. It really will have to get a whole lot worse before violence is deemed acceptable. (Note, not defending McViegh, just saying that was his reasoning.)
I already mentioned this a month ago when an article related to the legal fallout was posted: people checking in with firearms, air rifles, and paint markers is a common thing across the nation in the US. There is even a large, fairly well known training site just outside Las Vegas. You add hunting trips and competitions, and you start to realize even if you don’t see it or like it, it is pretty common. (not to mention all the CCW carriers.) This is why it is perfectly legal to fly with a firearm, just have to follow some protocols (checked in, locked, etc)
In this case they had no idea what the guy was bringing in as he did it over multiple days with regular suit cases. But I would also contend ONE event shouldn’t make the TSA move into the hotel lobby.
