> You can probably see where this is going.
Yeah, I can. It will get to about 49 or 50 senators (at the absolute maximum) and then stall out. Many of those senators, especially in marginal states like Arizona, will then become subject to difficult primary and general election challenges, dissuading anyone from trying again anytime soon.
> It is absolutely not impossible for 2/3 of Congress to agree on a controversial topic.
Provide even one counterexample, then.
> Believing that is very defeatist.
Yes it is. I’m a defeatist on this subject. Things don’t magically become possible because you really wish they were. Sometimes defeatism is the factually correct position. But you’re making moral/emotional arguments, not factual/logical ones.
I’m also a defeatist on such subjects as whether I’ll live forever, or whether I can win the lottery and stop working, or whether Iran or Hong Kong will become a democracy anytime soon.
