I almost listed a few of his activism and fundraising initiatives, but then I thought: If this person doesn't think a nearly 90 year old gay man, who survived an internment camp, has seen some shit and has some wisdom to share, I probably won't be the one to open their eyes.
Thinking about an issue is already an implicit action point that you're forced into by reading about it. Also, it motivates further discussion out of which ideas can emerge. Naming problems is valuable by itself.
Okay. Here's a concrete solution on a small scale:
