Prevent people from modifying my political statements or personal views which I included with the text.
There are two reasons I can think of which would motivate this want.
- You don't want people ascribing to you opinions that you do not hold; ie to prevent misrepresentation.
- You want to make your text available on the condition that it contain your political statements and/or personal views; ie to use your document as a soapbox.
If your motivation is the latter, then I consider your terms to be restrictive; it would be appropriate to include your document in the non-free section of Debian. If your motivation is the former, however, then copyright isn't entirely relevant. You could put your work in the public domain, and if someone created a "derived work" which misrepresented you, then you could sue (or threaten to sue) for defamation rather than copyright infringment.
The whole business of suing people isn't very nice, but it boils down to a question of what you are going to sue them for: copyright infringment, or defamation. If you think your chances are better at winning a copyright case, then by all means use copyright, but don't be deluded into thinking that such a restriction still allows your document to be classified as "free".
