Your invited. Why do you feel an expectation to like it or participate? Coming from a family of war fighters and veterans and being a Christian, I watch people not participate, in any serious way, in Memorial Day, Veterans Day, Christmas, etc. They don't affect my celebration and I don't give a fuck how they spend their time.

So if a government decrees a holiday, you feel compelled to participate? Some how I doubt that and wonder that makes this different other than the current times and political environment. Who is making you feel this way?
