It's a false equivalence, anyway.
If you're the opposition party, if the government is;
A> trying to provide a moderate compromise, it behooves you to play ball and cooperate in finding an appropriate compromise you're both equally unhappy with.
B> ignoring your views to do whatever they want, it behooves you to oppose every move you disagree with, with every political tool you have available. This is how you convince them to go to Option A and get some compromise going on.
Under Obama, his government was mostly pursuing Option A, and the Republicans weren't playing ball. Refusing to confirm Garland for SCOTUS was a clear example; Garland was a highly respected moderate who both sides had lauded in the recent past as a good choice. There was no reason to oppose that pick, from the Republican's side, other than to play stupid political games.
And now that the Republicans are in power, they're mostly pursuing Option B, so the Democrats should be opposing it. It's not comparable. If the Republicans put Garland forward and the Democrats opposed it, that would be shenanigans I'd condemn, but not what you're seeing right now.
