I understand your point, but don't feel bad about one mistake. It's not the little mistakes that count, it's the lifestyle choice that counts. Take them back to the shop for a refund or exchange if that's possible.
But, if you can't take them back, think about wearing them because to waste them is wrong, and two wrongs don't make a right. I did something similar myself not long ago. I usually only buy/eat chicken if it is free range, but I stupidly bought a chicken that wasn't free range.
After I realised what I'd done I ate it anyway because what good would it do to throw it away? But since then I'm much more careful about what I buy, just as you will be more careful yourself.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
