It's still a bad idea no matter what. It's based on the fiction that the Senate is some great deliberative body. Maybe that was true at one point (again, doubtful), but that time was fairly long ago.
I would be less opposed to the filibuster if it was used only to block monumental changes without more than bare consensus. You know, the way it used to be deployed -- for exceptional circumstances only. Give the minority party one filibuster per year.
One of its worst effects is the way it clouds responsibility in our environment. To those of us who follow politics, we understand that there's not really a Senate majority without 60 votes. But you constantly hear American voters saying things like, "the Dems had control for two whole years and they did nothing with it." Well, they had a majority but they didn't have control. Explaining that to people who don't follow politics is excruciating. In fact, even explaining it to people who do follow politics can be maddening. I can't count the number of times I've had to remind my mother that stuff doesn't get done because it takes 60 votes, except for reconciliation.
