Any gaff the Democrats make, whether intentional or not, everyone is on them for not knowing better and being disappointing.
I see no reason not to do the same for the Republicans.
If they can try to bring down President Obama and the First Lady over the
Terrorist Fist Jab, I can marvel over the Odal.
a) The "terrorist fist jab" started as a random user comment on the internet, it got picked up as something to mock by the media. A Fox News anchor used the phrase as a pre-commercial "you'll have to stay tuned to find out if this is a terrorist fist jab", and it wasn't in the actual piece, and the anchor apologized for it, and then lost their show for it anyway. This is not a good example of the right being unfair to the Obamas.
b) There's a difference between being on someone for a gaff and making accusations of malice. When Joe Biden says "poor kids are just as bright and just as talented as white kids", that's a gaff that he was deservedly mocked for, but nobody to my knowledge was suggesting that was a deliberate statement secretly intentionally showing other racists how racist he is. It's one thing to say "look, their artsy stage design is moderately reminiscent of an obscure symbol that Nazis used, what a funny gaff", it's another thing to fill a thread with "oh, they're using Nazi symbols to show how racist they are, I'm not surprised."
Edit: The CPAC stage isn't the same shape. First, the shapes are upside-down from one another. Second, the rune is made of a continuous line of constant thickness, but the central square of the CPAC stage is wider than if it were the empty space surrounded by the lines, so the lines change thickness, unlike the rune. The rune has short tails, about half the length of the center square, where the stage has tails that stretch almost as long as the center stage. The tails of the rune turn up about the thickness of the line away from the center square, where the stage has more open space than that. And probably most notably, the stage has an extra segment connecting the two tails that isn't in the rune ever at all. If they were drawing an odal rune, they did a really crappy job.
