I had somewhat of existential crisis after watching "Cowspiracy" and immediately gave up all meat for a few years for what I anxiously decided was for ethical and environmental reasons.
I did it because I felt guilty, then I watched more documentaries like it and made myself feel more responsible and guilty for everything.
One day I just "woke up" and started eating some fish and chicken. It felt good, not at all because I ate animals (I don't love the ethics of this), but because I no longer felt guilty for eating food.
There are some behaviors and activities I think as individuals we should maybe feel guilty for being involved in, but I don't like the way people are made to feel guilty for just doing the basics.
