Except for material that literally breaks the law, I tend to favor unfiltered free speech. One exception: sometimes people leave comments on my blog that are not about my post, but rather, links to their products, services, etc. I don't accept those. I don't feel like I need to support other people's free speech in these cases, on my blog.

I may be old fashioned (I have been using the Internet since about 1982), but I really think everyone should have their own web site and/or blog to post their own stuff on.
