I don't sing many "political" songs. I believe music is an extremely powerful force for the dissemination of ideas. A good song can get you singing about ideas that you really don't agree with. Witness the music in advertisements. Do you ever find yourself whistling the tune of a product you detest? The Nazi's had some wonderful tunes!So, I respect the power of music. I don't profess to know the one way the world should be. I hope my music helps me and perhaps my audience understand our own humanity.
I understand those who proselytize with their music. It is an excellent way to spread ideas. I encourage those who want to do so, to continue it and I will be happy to listen (and sing along) to many of those who have been mentioned earlier in this thread. There are many ways to try and make this world a better world. And each of them requires some type of courage.
Certainly one courageous way is to write and sing songs about what one believes.
