I totally agree - my kids had Berenstain Bear's books (as random gifts and such) and I would avoid reading them because in particular the way they portrayed Papa Bear as a bumbling fool grated on my nerves. He's like a Homer Simpson without the heart. I'm certain mothers also don't appreciate the way Mama Bear is portrayed as always in the kitchen and the ultimate authority figure.
If these books were updated to modern sensibilities I wouldn't have a problem reading them to my kids. As it stands, I skipped them and they weren't a part of my children's upbringing. I don't mind.
