I can't speak for OL, but I've said the same thing in not so many words several times. My objection is that the people spamming out this message are, well, spamming all over the place. Instead of encouraging dialog and thought about the proposed legislation, they're just saying "Don't think about it, we've done all the thinking for you, just pile on".
That
irks me.
Our Bible reveals to us the character of our god with minute and remorseless exactness... It is perhaps the most damnatory biography that exists in print anywhere. It makes Nero an angel of light and leading by contrast.
