I know when I and my family go camping it's because we want to get away from our house and distractions and enjoy the outdoors, usually with another family that we hangout with. Those other reasons you listed are there because someone may not understand that so they inject other reasons into your activity and can't fathom it is for any other reason. If I do an activity like commuting (which I do) for my personal reasons yet I hesitate because I'm concerned with how it may appear then I am contributing with an issue we have in the world. It's allowing other people's views affect what you do when you know you are NOT doing your activity for the reasons they have a concern.

I am on control of my life. I don't allow others to use puppet strings on me.
