Speaking of ignorant comments, the Senate rules are adopted by majority rule. McTurtle could have changed any rule by just his own party...if he really wanted too. But as I said, he really wants to work as Harry Wirdo's replacement than do what republicans should be doing.
Not sure what you're pegging as ignorant, but there is not at the present time a Republican majority for changing the rule. Try to understand why. First some background and context: The filibuster rules as applied to judicial appointments were amended by bipartisan agreement a few years ago for judges short of the SCOTUS, and McConnell used his majority to get it extended in time to allow Gorsuch to win confirmation. Don't kid yourself - if you value Gorsuch's being on the Court, then thank Trump for nominating him and McConnell for forcing through the rule change. It couldn't have been done without the both of them.
The thing about abolishing the filibuster rule generally is that some Republicans just happen to be risk averse; they know that at some point they will be in the minority again and the filibuster is THE tried and true method for the minority to stymie the majority.
You want to condemn them for that? Then consider what happens if the Dems retake the House in 2018. Don't think that can't happen? We have a loose cannon in the White House; I say pray to the stars it won't happen. And if it does, then Trump gets impeached and it's the filibuster rule in the Senate that keeps him from being convicted and removed from office.
