Jean Harlow or Marilyn Monroe?

There is a famous picture of Jean Harlow that if you showed it to young people today they would say oh that is Marilyn Monroe. Which totally floors me. I just saw a movie of Jean Harlow last night and I don't believe she gets the credit she deserves. Don't understand why people think Marilyn Monroe was so great. I mean she flirted and went after married men. She wondered why she didnt have any friends? Before you say oh you hate her cause shes beautiful, uh no there are many beautiful women and they dont go after other womens boyfriends or husbands. Marilyn Monroe made no secret that she loved Jan Harlow and it bugs me that some people dont even know who she is. I thought she was an amazing actress and I also happen to enjoy Marilyn Monroe's movies. I think she was a great comedic actress. Why do people make her out to be a saint though?
