How is not putting up with negative comments force feeding? If someone doesn't like it then don't visit. If it's your blog, your domain then I feel like you should decide whether or not you want to put up with that stuff, I mean it's your blog why let others make it something you dread or don't enjoy. Like you have some sort of obligation to make it slightly miserable for yourself? I do allow comments but have a report button there.
Some people just don't want to waste that kind of mental energy on negative posters. If you get people saying
"that's ugly" or something along those lines then it's useless I'm more prone to listen to people who say
"this is ugly and here is why..."
I don't know, I just think blogging should be something fun.
