Yeah but Trump made a hand gesture like that, in a rather recent photo, or recently posted photo. I don’t think it always means something sympbolic. I remember when the “devil horns” hand gesture was making the rounds - hand with forefinger and little finger out, the middle two bent onto the palm. It’s a gesture I often make when thinking or whatever. I don’t do devil worship. Sometimes a hand gesture is just a hand gesture.

Not to mention the White People hand sign, or the “It’s OK to be White” symbol.
Public speaking training.
“What do I do with my hands?”
Or, “What NOT to do with your hands.”
1. Never in your pockets.
2. Never point, directly.
3. Never interlock the fingers.
4. Make a point stronger by raising your hand. Even stronger if you can draw attention to your hand by finger movements.
These are all devices used by professional rhetoricians.
#1, Trump never points when addressing, he will point prior/after his address
#3, interlocked fingers indicate “holding back” or “defensive”; arms crossed over chest = same.
#4, Trump uses several devices for emphasis; hand-chap, hand wave (sometimes in specific shapes) or circling his fingers together. He will combine these.
