Spending time with family, creating / learning / doing productive stuff are all things we should be doing and help not only our personal wellbeing but advance the ideas and spirit of liberty.
I disagree with your characterization of the anti war movement however. Politicians listen to their constituents to the extent that they want to get reelected, and if an issue is so unpopular with the people it will affect the decision making process. Strong anti war sentiment helped end the Vietnam war, Afghanistan, and kept us from escalating in Iran.
Rather than "badgering" people or "patting each other's backs", when I see hundreds of thousands of children starving in Yemen and dying from cholera and other preventable diseases I am disgusted and feel compelled to speak out.
It's your life though, you do you.
Looks like they updated it since I posted the link.
