I hate to be the one to say this but even though many are not happy with the US election results, this is the democratic process in action. The voters have spoken and like it or not it is what it is.
Protests and flag burning may make some people feel better for a short time but they won't change the results.
I may not agree with how some people cast their votes but many years ago an awful lot of people who we will never get to personally thank fought for our rights to vote as we please and I would challenge anyone who wants to take that right away.
The US Electoral College and election system is one of the wildest systems I have ever seen but it was created by a group of people much smarter than I am and has been in place for over 200 years.
What everyone CAN do is to become involved. Hold the elected representatives accountable and show them that you are watching and paying attention and they should stay on the proper course of decency and good.
Even better, do as I have done. Run for office and keep an eye on things from the inside.
