Again he has literally been yelling about Israel's war crimes and the need to stop funding them on the floor of the US congress since I think the 1990s. Again you are being taken in by a fantasy-world designed by people who want you to stop supporting leftist voices in the US congress, which helps to defeat some real efforts to help save the Palestinian people before it is too late.

Again I know you're not deliberately trying to hurt the cause of the Palestinian people, but the people at the root of creating this stuff you're being taken in by are (or at least they're indifferent to it if it can hurt people on the left), and you are unintentionally helping them. Your "simple as that" is just wrong. Again that's all I can really be able to relay to you about it.

See! I can do that too, just decide what the important parts are, and take the part of the person who is speaking and attempt to force the other person in the conversation to be the person listening, by just repeating what I said before.

I would actually say that recognizing his current legislative actions as far as punishing Israel, removing funding, otherwise trying to do something to help the Palestinian people, instead of just performatively flopping around and clinging to particular less relevant facts as a way to complain about someone who should be an ally, would be better. But you do you. Want to do it again? You can just copy-paste your message and say "Again" in front of it, that's super productive engagement and will help.
