The meme is not wrong, but we leftists have refused to be electorally active and as such have surrendered unconditionally any influence on policy we could have.
It is not about blue no matter who. We should organize to build a progressive party and support it so that we can get candidates we want. Mamdami is an example here. Still if you live in a place were that is not going to happen; then blue no matter who has some reason to it.
We don't participate electorally and we don't help people move to a parallel economy to escape capitalism. We just post smug memes like these and wonder why we are not a serious movement.

This time the orange man is finished.
Didn't ask, don't care.
Nooooo, you're breaking the rules.
I'm so god damn tired of watching this.
