When I was younger, I tended to stand up for other kids when they were being bullied. I don’t have a good recollection of all the individual times, but I remember several instances where the teasing got out of hand, or someone was getting picked on a lot, and I told their tormentors to stop. It usually didn’t take much, since this was usually when I was a smaller child, but sometimes it helped to be tall. Really tall.
On a more recent occasion, I stood up for a cause with thousands of other people, that cause being science. I participated in the march for science because I believed that the people of our country should not be fed lies and false facts by someone who is supposed to be a leader. The march was awesome. There were so many people out who thought like me and had relatively the same ideals. So many scientists from so many disciplines turned out to try and rally for many causes, from not tearing the EPA apart, to just having Trump admit that Climate Change is real, not lie about how it’s a Chinese conspiracy.
I guess you could consider that going to the protest was courageous, because you never know what is going to happen. It could turn out that some people decided to be violent in their opposition of Trump’s regime of stupidity, ignorance, and denial of scientific evidence. Luckily that didn’t happen, as it was peaceful and joyous. It was incredible being part of something bigger than just me, and it was also really fun making signs and getting ready.
