some people have a favorable opinion of Israel in spite of being against their genocide
So... people like, say... Joe Biden?
No, not people who are active participants in the genocide who have vowed not to stop no matter what.
A civilian who still instinctively supports Israel in general can simultaneously oppose the genocide. It's misguided, but it's the case of many voters.
In contrast, a PRESIDENT who sometimes says "hey, please cool it, guys!" but also IS AN ACTIVE PARTICIPANT IN THE GENOCIDE WHO HAS VOWED NOT TO STOP can not in any way be said to be against the genocide that he's taking part in.
