OP provided their version of context. At face value, I agree with you. But did OP use a racial slur? Anti-Semitic talking points? Did OP call for violence or threaten someone? When I say OP didn't provide context, I mean they didn't provide anything backing up their context. They just said they were banned for being critical of Netanyahu and Israel being engaged in genocide. It's been years since I made a reddit comment, but I know I made many similar comments back then and never received a ban, so either the mods were being feckless and arbitrary (certainly a possibility) or OP did more than they claimed. Either way, we're lacking the context to know either way.

I used to mod a few subs, and I can't tell you how many shitbags would come into the sub throwing slurs and threats around, only to blame us for overreacting when they were banned. That's like the default response to earning a ban. I also saw mods act like power-tripping toddlers who would ban anyone that didn't kiss their toes. My experience was more the former than the latter, but that's just my experience.

Context still matters.
