Well by being an ethical vegetarian, you are helping mankind by decreasing greenhouse gasses and saving water, especially if you are vegan. Everything is interconnected. The sooner people remember that, the better for us all.
As for cruelty free products, I don't support any corporation that exploits humans. I may accidentally purchase something, but I try to avoid Unilever, Nestle, Wal Mart, etc.
I'm honestly unclear on how clothes are vegan, outside of avoiding leather, and leather is not a product I ever really purchased for myself, though I wore it in the past because of relatives supplying clothes. Well, and not wearing feathers.
I mean are vegan clothing choices so limited that people are routinely forced to buy ones that exploit human workers?
I guess "buy local" is one of the safer ways to avoid this?
