While I could be wrong, I doubt they made up that salute on the spot or are doing it to harken back to 1915 nostalgia.

Nah, I doubt that was their intentions. I remember vaguely thinking "These people are dumb" then noticing the salute and remembering that little bit of trivia that most people don't know.

I can't remember all the dumb shit I've seen. It doesn't stay in my memory as there is too much of it. I see it all over the place from all parties, and labels.

Lately those protesting, and rioting though have added a burst of speed to their group and I can't keep up with the amount of stupidity I am seeing/hearing from that area lately.

There are smart people too, but man do they appear to be outnumbered.
