I think that the downvotes come from a place of not understanding what this comment tries to imply, hence not adding anything to the conversation.
For example. Someone can read this and think “Context matters, so that’s why Hamas did what they did, and what they did is fine and I stand with them”
Another person could read “Context matters, it doesn’t matter what Isarael did before, Hamas still did something unforgivable and Israel is still right and I stand with them”
Ultimately, at least for me, it’s hard to see what you’re trying to say with this comment, especially when the situation is so nuanced. At least that’s how I saw it.
