Your thoughts reflect a lot of my thoughts on modern activist culture. Being a baby boomer, I remember the civil rights movement and what it took to actually make things even a little bit better. I grew up with stories of the great labor battles and knew what my middle class upbringing rested on even as my parents protected me.
I especially like your closing thoughts on comfort. Comfort is indeed a great privilege. Too much is made of comfort, and not enough is made of actually changing things.
