I really wish we had a list of all legislation that Democrats say they oppose but then vote for anyway

We do actually, it's called the Republican party platform

In all honesty, probably not nearly as much as you think. Democrats aren't exactly making any effort to pretend to be against genocide or neocolonialism. They make a tiny bit of lip service towards social progressivism, and considering that Republicans are explicitly pro-trans-genocide, that bar is so low it's currently sitting in hell.

It's all just theatre anyway. Policy doesn't matter anymore, both parties are subservient to venture capitalism, just donning different aesthetics to appeal to different groups. Like the GOP will don a white nationalist aesthetic, but they love immigrants as a source of exploitable labor. The DNC will adopt a pro-minority aesthetic, but they love sending rainbow painted bombs to kill brown kids overseas.

Politics is just play, Capital is power.

Kinda related, but even the "socialist" on the democratic party are the same on external policy.
