I understand both perspectives. I think personally I wouldn’t mind wearing vintage leather as a vegan if I got it from family or so.

BUT someone explained to me (and I find that very convincing), that if you truly abhor the practice of skinning animals and wearing their skin, a leather item is something you really wouldn’t want on your person.

I’m not saying killing animals is the same as killing humans, but just for understanding that perspective, imagine a vintage item made of human skin. Yes, the victim was killed many years ago and you didn’t support them getting killed, but it’s still not something you’d personally want to wear.
