Well, I guess I break all the compost "rules". I've put meat, fish, chicken, turkery, dairy products, breads, you name it, in my compost bins with no problems. Some people even advocate composting human soil waste, but I won't go that far (although urine is fine). In a properly set up compost pile, any pathogens are killed by the compost process - both heat and compost bacteria/fungi.
I don't add rose prunings (the thorns don't break down readily) and certain weeds that have gone to seed.
It's also not necessary to wait three years for a compost pile to mature. One year is more than enough, and some people are able to shorten that to a few months.
