I think it's simply bad manners and lack of decency that makes people think they have the right or even a reason to attack someone on their own blog. Apparently it's just TOO grown up to agree to disagree and move on. There are plenty of blogs i've visited and didn't agree with, Be the subject, politics, religion, or anything else. I simply pull up my big girl panties and i either stop reading the offending post and move to another OR i just leave the blog and read elsewhere. It's quite easy.
What a nice concept! I wonder--would these negative-commenters be so rude in person? Probably not. They use the Internet as a shield and excuse for telling authors what they should or shouldn't write about--hello???--instead of being excited about an author opening up their site for comments and the chance to have some worthwhile discussion and opinions shared. Bad blogging manners need to stop! Telling a site author they are "stupid" for writing about a certain subject needs to stop! I know it won't, but it's a shame. Spread the Luv!
