That was a rude comment from someone reading your FB posts. If they don’t like what they see on someone else’s FB, website, whatever, they should make sure to stop looking.
FB people are the thinnest-skinned people on earth. No one is really your “friend” there. No one!
We conservatives know that but libs do not thnk like we do. I see a lot if things I am not interested in but that is what the poster likes so I just ignore it.
