"It quite clearly defies the Constitution, and the Constitution says Amendments can't actually do something contrary to what's outlined in the original draft."
Which it doesn't it's only a temporary thing that's going on, you'll be surprised that it'll go quite well. Plus, didn't you want this stream to be more active? Your way would fail.
"Amendments can introduce common-sense improvements,"
Exactly what Surly has done. Introduce common-sense to improve bills by making the bill process more efficient and a way to get our bills done.
"but not completely change the rules like this bill is trying to."
It's not a change, it's just a temporary motion, just for a little while.
While we're at it, you made multiple memes that are related to LGBT NSFW without a bill, you knew it would violate the constitution, you previously tried the bill going under your original account, but wanted that bill again because you told me on memechat empire that you wanted to "remove borderline p0rn" when there is no p0rnography on imgflip_presidents. You'd consider LGBT content p0rnography, even a flag for crying out loud.
