The difference between someone who only jokes of another race just to get a good laugh without having any negative feelings towards that race, and someone who insults another race because they harbor ill feelings towards them.

when you've done something so cringe you can't stop replaying it in your head and it stops you from getting on with your every day life

When you are racist/prejudice towards gingers, rednecks, and mormans, the only people that can be disgriminated against, without seeming racist.
