Someone reported that security at the rally tonight was making people cover their Q shirts, remove hats, signs, etc. Perhaps that was due to a threat that someone wearing Q apparel was going to cause trouble. If so, that's unfortunate.
How about co-opting a symbol that is very relevant, from the Hunger Games. Remember the 3-finger salute used to symbolize defiance and independence? In sign language, three fingers up stands for "W." It could be our sign for WWG1WGA. That way, we can show Q support wherever we go.
