Im so mad, i need to rant

So I posted a picture on my Facebook that says to be proud of your body for carrying children when some women can't. And I am proud of my body for carrying children. I mean I do feel bad for the women who can't but why can't I be proud of my body openly? My brother commented on my post saying I offended 1/3 of the world and he called me a dumbass. Why is the country full of some people who always have to make themselves the victim?
