Free Speech

The first amendment protects: freedom of religion, freedom of speech, freedom of the press, freedom of assembly, and freedom of petition. These freedoms are however subject to limitations. Notably laws against defamation, and incitement of violence or rebellion. For example it is still illegal to block polling stations even though we have freedom of assembly.

There is no clear line that defines when something passes from utilizing the right of free speech to becoming harassment. Harassment is generally assessed by asking the following questions:
1) Is is specifically targeted at a particular person or group?
2) Is it a repeating occurrence?
3) Is the speech intimidating or threatening?

No, the first amendment does not protect civil disobedience on or off campus. The incitement of violence and rebellion is specifically referenced in the first amendment as not being protected or allowed.
