Just a thought regarding your pic….
I use the same/similar hand gestures when I am being precise in choosing my words and am emphasizing the precision in a conversation. I'm 100% Christ Jesus all the way and I don't consider my hand gestures luciferian at all. Trump might not be using "their signs". It might just be his way of kinetically connecting his body and his thoughts as he maps out his way through a speech. Body gesture can be very useful for some to help with choosing and structuring thoughts on the fly as they speak.
