I don't support Harris, but I will vote for her because Trump winning will only make things worse. And accelerate the climate catastrophe, which will hurt everyone who lives here, animals and plants too.
As far as how I will get the US to stop funding Israel... I won't. It's a bigger problem then myself.
But, organizing outside of the election cycle is the way to do it. Protests, strikes, not paying our taxes. Those are the ways to change things.
A third party protest vote won't change anything. It will just get your candidate and those who voted for them blamed for spoiling a two party election and putting Trump in office.
P.S. The framing of your question sucks btw. For reasons I pointed out above (I don't support Harris, and I don't propose that I can do anything personally to stop the genocide outside of organizing with others. And, if Trump is elected, the genocide will accelerate and likely spread to other middle eastern countries, and everyone will be suffering greatly by 2075 due to climate change).
I think I would still enjoy some their newer titles.
I just don't think I would enjoy them enough to deal with the predatory behavior from the publisher.
