Why do some find it acceptable to tell others how to express their emotions/feelings?

I suffer with infertility personally and occasionally yeas loose my cool when people post about how they don't want the child they became pregnant with. Or that they don't understand how sexual relations get them pregnant even if he didn't "cum". 
Yes it angers me that people are so ignorant about sex! If you're not old enough to know how it works then you're not old enough to have it... Simple as that. If you're not able to care for a child or you don't want a child use protection. Obviously accidents happen and even when using protection it's possible to still become pregnant but to flat out refuse to use it or don't use it just because you don't want to. That's what upsets me! That's what makes me angry. To be so immature with such a serious serious thing... That's not ok! 
Yeah I may lash out at those who are so ignorant to make these decisions but all in all... Who else is gonna stand up and let them know how insanely immature they are being. Also how their actions have an impacket on other people. How their mistake and unwanted child is breaking the hearts of women and men everywhere who can't have a child of their own! 
If I have ever hurt you by the things I said I'm sorry... But at the same time I'm not. Please use your brain... Learn about sex and what happens with the body before you actually partake in the act of sex! 
That's my rant.
