I must be older than you. The First Amendment guarantees your right to speak about your government without fear of reprisal. It has come to mean that anyone can say anything they feel like.
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.
