I just joined in Dec. 2010, but as far as I can tell, speech is pretty free on the Board, so I doubt that you will be banned, you are entitlted to your opinion.
I can imagine that things have changed. With 250,000 users, the site is probably very different than it was when it was smaller. Your goal of reading every post is probably unrealistic now.
I also don't care much about new babies, most old sewing machines (although I love to look at FWs) or Bow Tucks, but I find that I can pretty much ignore them from the titles, or click, then quickly click away if the post is not interesting.
Sorry that you're feeling bad about QB. The joy is that you can participate or ignore, as you see fit.
