Self censorship is always an act of self preservation, regardless of the current political climate. If people had felt that way about civil rights, do you suppose women and ethnic minorities and African Americans ever would have gotten their civil right to vote recognized (just to cite one example)?

The point is, you are supposed to move beyond the self preservationist's complacency, and stand up for your beliefs. Pick and choose the battles wisely, but don't base the decision on whether or not people will disagree/dislike you for simply speaking your mind. No one will respect you as a musician or as a human being if you can't stand up for what you believe in.
