Why is everyone hating

On the person (possible troll) that posted saying she's 16 and pregnant and the father could be between 7-10 guys she slept with ??
Not too long ago there was a post saying you can sleep with as many men as you want, who are others to judge bla bla. 
But now I'm reading comments on that okay sayings it's unladylike and inappropriate to have that many partners. 
How the tables have turned??
