All I ask is this: Do something. Try something. Speaking out, showing up, writing a letter, a check, a strongly worded e-mail. Pick a cause — there are few unworthy ones. And nudge yourself past the brink of tacit support to action. Once a month, once a year, or just once.

– Joss Whedon, writer and film director (b. 1964) 

Now how could anybody disagree with that? I would add one caveat: do a little reading and thinking first.  Try to clear off a small plot of mind for the task at hand. Stupidity is one of the most contagious diseases threatening our species. Here’s a particularly serious case, by the name of Mark Williams. Seriously, wow.
