What do you do when you find out that an awesome person in your life has a really stupid or detrimental belief?

Yes but everyone has a right to their beliefs. Right or wrong in our opinion. We still have to love our fellow man, woman, brother, or sister. Otherwise hate blooms and chaos flourishes. As Carissimi stated, just agree to disagree and drop it.

I had a very dear friend that had racist views and didn’t even realize it. It was very shocking. I tried to just let it go but it was always there and always bothered me. We are distant now and it’s prob for the best.

Yes. It was very upsetting, but I had to let it go. No good comes of it. You just have to realize you disagree, and get past it, if you want to maintain the relationship.

What is the belief? Your brother may not see it that way.
