The Fourth of July committee's proposal to censor the parade is awful. The Fourth of July parade is precisely the time and place for political or personal opinions of all stripes, and the more the merrier.
Although my personal favorites in the parade are the marching band, the bagpipes, Dale Wygant on the accordion, and the Filipino dancers, I have always been proud that any individual or community group could join - dogs, clowns, kids on bikes, religious groups, politicians, boring entries, outrageous entries, and those with a political message.
For me the parade is a yearly celebration of the First Amendment and our common ability to put up with one another, even when we disagree. Anyone who is offended by a particular parade entry is free to refrain from applause. We in the land of the free and the home of the brave do not need to censor our Fourth of July parades.
