On the anonymity of the internet
This anonymity has downsides, of course, one of which is that there are no consequences for what you say. Oftentimes this fact frees people to say the most horrible, hurtful things imaginable, like "I'm glad you had that miscarriage, you deserved it." Or "you're a terrible mother and I'm sure your children hate you." I see this happen on blogs all the time. A blogger will post an entry and, if the site has a great deal of visitors, there will be at least one commenter who says something that they would never say to a person's face. But the internet provides a sort of shield in that way, that you can say what you want and not have to face the music.
The good news is that there's an upside as well. One of the things I find so freeing about the anonymity of the internet is that you can find out things about people bit by bit and allow people to find out things about you bit by bit. This enables people to get to know one another as human beings instead of a collection of labels that, in the real world, might prevent them from getting to each other in the first place. In effect, it allows everyone to illustrate that they are so much more than the sum of their beliefs. And I think there's something really lovely about that.
