Horrible comments

I hate to even give this any attention because I don't want to give whoever this person is the satisfaction of knowing he or she bothered me. But, I want to say that it's incredibly cowardly to post horrible comments on someone's blog anonymously. What in the world do you know about me, my life, my daughter, and her birthmother? Nothing at all. Your lack of facts in your comments prove that. My daughter's birthmother was NOT on any medication when she decided to place. She was not coerced in any way and to imply that she didn't make the decision herself is taking away from her strength and courage as a young woman and mother to two young boys who she was struggling to feed when she got pregnant with our daughter. Deciding to place Lily was the hardest thing she has ever or will ever do; I'm sure. And insinuating that she wasn't in the proper mental state to do so is grossly incorrect. How dare you presume anything about her or about us.
I'm sorry to my blog pals and kind readers who have offered me nothing but support, but this makes me shake with fury. I don't want to go password protected because every week I get posts or emails from people new to adoption who feel just a bit less alone because of blogs like mine. But, I also don't want to have to wake up to evil comments, either. I probably should have waited to post until I thought more about all of this, but blogging is my therapy in lots of ways, so I'm not going to censor myself. Is there any way to avoid password protection by disallowing anonymous comments? Can I require people submit an email address? Again, I'm sorry for this little outburst, but it pisses me off so much. I know lots of you have gone PP - any advice on getting these commenters to at least have to be accountable for what they post?

Edit: One more thing I want to make crystal clear. Autumn was in no way, shape or form forced to sign consent 24 hours after the birth. She is the one who scheduled the signing time - not us and not the agency. Utah law says it is legal for a woman to sign 24 hours, but she is not required to. She can sign a year later if she so chooses. Another fact this commenter chose to ignore or skew. That is all I will say about this. I hope:)
