If she sees this comment though... might speed the process up

Excellent 5D chess move

But on a more serious note, this sounds like an infinite fountain of resentment for the two of you. From the outsider POV here, it's easy to say "just leave." But as someone on the outside who has been on the inside... you gotta take action. Now or later, this stuff tends to explode.

Results will be a quick burn end of the relationship or she comes to acknowledge the truth (that criticism of Israel doesn't inherently have anything at all to do with Jewish people. And also thinking it does is into itself pretty antisemitic even if tons of people think it anyway). You either save yourself years of internal torment and resentment (and probably same on her end, to be fair) or you have a healthier, more mature relationship where you can respect each other and learn and grow together.

It's your life ultimately. Why spend it with a hovering cloud of resentment over your main relationship and source of human contact? Unless it genuinely doesn't bother you. Then do whatever. Do whatever anyway. It seems to bother you though considering draws circle this whole-ass post.

And the sunk cost fallacy is a bad logical fallacy with investments and such. When using it regarding a relationship... it's only going to get more "sunk." More cats, maybe kids, who knows. I don't want to boil relationships down to dollars, but it's safe to say long term committed relationships don't tend to have partners become less "bought-in" over time.
