"If you have concerns about this but were OK with McConnell refusing to even give Merrick Garland a vote, you're just a Republican hack and should stop pretending you have concerns about the Senate as an institution."
I never agree with being told what I have to think about something. I didn't vote for Trump, and I'm not a Republican, but nuking the filibuster could end up trickling to all filibusters. I think it has many more far reaching implications. Not voting on Garland, while silly and annoying, has a long history of precedent from both parties.
TL;DR They both stink, but this is concerning.
