I dislike things where taxidermied animals parts are used for something because it looks weird. Like animal legs and feet for tables. Basically if it makes me think the animal suffered I dislike it.

Yes I eat meat and wear leather and other stuff from animals that often makes them suffer, but I also spent a large amount of time on grandpa's farm and the idea that ethical use of animals can exist overrides my knowledge that they are often abused in my day to day decision making.

I think learning about Nazis making human skin stuff out of their holocaust victims put me off for things made out of human parts. Like bone is bone, but my first knowledge of human parts being used was Nazi ahit. Didn't find out about the religious human remains stuff till later.
