I never comment about a persons size, colour, faith, sexuality etc. it is none of my business what other people are like, unless it effects me. When I was a manager at a supermarket, I had to pull one of the staff in due to his awful B.O. I tried to deal with it sensitively, customers were refusing to go down the aisle he worked on, and he smelt like rotten Stilton cheese. Generally though, I say live and let live.
