Your choice is if you'll willingly accept the burden and do whatever you can nonetheless to help the most people domestically and globally -- or if you'll pretend you aren't carrying the burden, and you're willing to throw women, black Americans, brown Americans, gay Americans, trans Americans, etc under the bus to maintain that delusion.
No matter what you do, if you pay taxes in the US, you're funding infanticidal Israeli weapons. Democracy is shitty like that. The majority of people are uncomfortable with all the civilian deaths, but a majority still wants to fund weapons for them. Don't like it? Grit your teeth, try to make a difference, and minimize any unnecessary support to Israel.
