Well, that's a ridiculous thing to say, and really not worth responding to.
The poster sincerely compared voting for Gorsuch to the Munich Agreement, I think 'ridiculous' was deserved in that case.
It's astounding the number of people who want to see this guy blocked. Gorsuch isn't Bork, he isn't a Trump crony, he isn't a nutter. He's a guy with conservative opinions who is perfectly qualified to be a SCOTUS judge.
Plenty of Republicans voted for Obama appointed judges, because they knew they were qualified and Obama had won the election.
What the Republicans did to Garland was shameful, their obstructionism throughout Obama's presidency was reckless and stupid. However, like it or not, the SCOTUS has become politicised. Can you imagine a Democratic Senate allowing Bush to appoint a replacement to Justice Ginsberg with 9 months left before the election?
You're wrong to want the Democrats to follow the GOP down this reactionary path. The right can do things that the left will never get away with. For example, imagine the reaction if a Democrat had restarted the US relationship with communist China, instead of Nixon.
The whole period between 1968 and 1992 is clear evidence that Democrats only win when they're capable of being trusted by the centre ground. Poisoning their legacy of responsible governance is the last thing Dems should be thinking about.
