In America, Freedom of Speech means the government shall not pass anylaw prohibiting anyone from speaking out against it.
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.

And yes, this is a private forum board, and can be edited and have posts deleted, legally, at any time.
