Ways to show solidarity edit
A: Indicate with their right hand towards their left upper arm:
Whenever a soccer player thinks at it and has time, he could hold his right hand such that his index or complete hand indicates towards his left upper arm, where the arm band should be, even though these players are not allowed to actually wear such arm bands.
B: Digital inserting/dubbing:
Western TV studios could digitally insert the arm band(s) to the upper arms of those captains and players who have uttered that they wanted to wear the banderole but were forbidden or threatened to wear them.
C: The French gesture:
The French have a gesture (which means something comparable to the middle finger): they bend their right fore arm half way, lift their right arm and while lifting slap with their left hand on their right upper arm.
This could be done mirror-wise, indicating to the left upper arm where the arm band would be.
D: Uni-coloured t-shirts sitting side by side:
Fans who are in the land could wear a uni-coloured t-shirt (red, green, yellow, blue, pink), go into the stadium seperately from each other, then sit down side by side so that their t-shirts, seen by the TV cameras, give the impression of a rain bow or just a multi coloured appearance.
