For me, it always has to be about health. That's why I'm a vegan. Well, I don't even do that for my health entirely, I do it for animals.
Confront your fears, list them, get to know them, and only then will you be able to put them aside and move ahead.
But, you know, the issues of humanity and what is fair treatment and good treatment of a fellow human being should not really be based on a personal sense of right and wrong or judgment.
