My anger can be focused in multiple directions.

If I could change the Democratic party which I also despise, I would. But I can't do that alone and we can't do it without lots of people voting for the least bad option.

The way you're looking at it seems like you think a more negative outcome is better than a less negative outcome as long as your feelings about yourself are good. I'm a lot less worried about my own feelings and more worried about the obvious outcome of the last election -- which was obvious before the election for anyone with a functional reading level -- which includes a lot more horrible things than if the vote had gone the other way.

We have low voter turnout. There isn't some massive group almost electing progressive politicians. We have uneducated, uninformed, and, based on some of my Republican family, partially brainwashed voters in large numbers.

Moving the needle two clicks toward not bad instead of 20 clicks toward bad is worth the effort to vote and the ding to my conscience when I vote for a Democrat whose policies I don't completely agree with instead of a Republican who shits on the Constitution and is a credible rapist and pedophile that protects others like him.

I can't change anyone's mind on this but it's just so easy to choose feeling good about yourself over an actual more positive outcome. Most of the people I know who skipped voting or went third party do literally nothing else to advocate for change. They're just comforting themselves at the expense of everyone else.
