Afraid to tell it like it is!!!

I read a lot of people's post and I have always been a straight forward tell it like it is kind of person.  Everytime I go to tell it like it is on here I stop myself because a lot of people are sensitive.  I take that into consideration but I really want to start telling people on her to quit complainting because their life could be a lot worse then just their insecurities about themselves.  I mean who posts what selfi should I use?  Really??  I am bringing to think a lot of woman are needy on here
