Have I heard stuff? Unfortunately, yes. Have I experienced this? No, not noticeably, I would probably have a "chat" with the pilot and end up getting kicked off for telling him my view.

Do I think they will be able to organize anything big enough and actually follow through with it? Nopers.
This kind of idiotic protest is ridiculous. The "let's show them attitude" is inconveniencing us (the passengers) the most, and we are NOT the enemy. Why can't they understand that?
