Just glancing at the First Amendment to the U.S Constitution:
"Congress shall make no law respecting an establishment of religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press; or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances."
I notice that the the amendment does not require those who peaceably assemble to be clean shaven, much less clean. Nor do they have to be nattily dressed. They needn't be employed or have reached an age that you find appropriate.
You may or may not agree or even understand the issue.
Regardless, you should be concerned when the government turns on its citizens exercising one of our most fundamental rights.
