Not the person you are replying to, but I think the logic is a bit different than “is it politically good or bad.” It is more like “is this speech advocating for genocide of an ethnic group or is it just critical of/disrespectful to a religion.”
I think most people agree that those two things aren’t even close to being the same. Also, I don’t think that “talking negative about islam” has been a “politically good” thing in way over a decade.
It certainly could indicate support for genocide. It also could indicate extreme disapproval for the vastly disproportionate civilian death toll among Palestinians at the hands of Isreal in the wake of Hamas' attacks.
It appears to me that Israel's goal under Netanyahu is to suppress dissent, and label all those who oppose its actions as "genocidal" to therefore justify its indiscriminate violence against the people of Gaza.
