Arabs dont have equal standing and treatment in israel. Also, Israel is increasingly far right and best estimate is less rights in the future.
I agree that we should hold Israel to highest standards (which are, unfortunately, eroded especially by the US, these days).
Nevertheless, you should always ask yourselves: would you prefer being an gay Arab in Tel Aviv or a gay Jew in Gaza?
There are 2 million muslim, mostly arab, citizens who are officially and legally equal to jews. They are distinct from the arabs in Gaza or the west bank, who are not citizens.
