Why do grown adults think it's OK to talk about little kids?

Anonymous
Since I was 7 I noticed adults thinking it was ok to talk about little children. I was at a cookout sitting at a table with my mother sister and my aunts friend. my cousin walked pasted my aunts friend and she randomly said my cousin was fat and sloppy. 4 years ago I was dating a guy and we got into a argument and he called my child retarded and most recently my ex called my child dirty (they where the only 2 guys I brung around my child and I don't plan on introducing her to any other guy I met unless I'm engaged) why do adults think it's OK to talk about children.
