Apparently I can't be a Mother....EVER. WTF?

So I cannot handle the amount of people who forbid me from having kids. I recently on my other blog(comment not posted) received a comment on something I wrote about a year ago about Glenn Sacks. It was one of my posts against MRA's(Men's Rights Activists) and someone commented. I have reason to believe it is a man, because why would a woman yell at me about women's work ethics? This man also posted anonymously because that is the only way men like to attack me. At the end of it he declares that he is praying to God that I will not ever be able to have children(male or female). I find that offensive! If I said that to ever person I dont agree with, I dont know if anyone would be allowed to reproduce, hell I wouldn't be born... This wouldn't bother me so bad if I didn't get told this at least once a month, often by people who claim to be my friends. Sure for a while I didn't plan to have children and I didn't want children, but things change, people change. I might want to have children, and to have people say that I would be the worst mother ever, really bothers me. Of course no one would understand how that is hurtful to me.
