How is abstaining better than voting? 

You think that a Biden win is worse than a Trump win?

If Trump wins, its Biden's fault and thee genocide continue. If Biden wins, the genocide continues. Do you want to pick either?

And if you abstain then Trump wins. 

The ongoing genocide does not take away the many good things the Biden administration has done.

I think it's also worth noting that the genocide gets WORSE and probably CONCLUDES with Trump in office. 

Your virtue signaling that 'genocide Joe bad' falls on its face.
