The point being made for this stream is that if one wants to help humanity, the world, nature....one must rebel against that which is endangering humanity, the world, nature. I know you like to encourage people to believe in Jesus....his disciples were rebellious against the norms. While Jesus wanted to help humanity understand the power of love, He had to rebel. He rebelled against Evil. Because He had a mission. How did He rebel? By tapping into His higher qualities (back to the meme).
I always thought they were saluting. I don't think facepalming would have been drawn like that at the time when his comic strip was in the newspapers. They look like soldiers lined up to salute Calvin's Dad when he was walking up the path to the house...also like saying "Yes, Sir!"
