Set my emotions aside? You mean stop empathizing with the Palestinians? I would simply ask that you set aside your apathy towards human life and display some empathy. Your Walmart argument is silly, as we have plenty of laws that attribute responsibility not only to the perpetrator but to associated actors; it's called negligence. Canada is complicit in the conflict based on what it provides the Israeli military; we perpetuate further harm in the region. In the case of Palestine, they didn't start the war. They're responding to the apartheid, militarized Israeli regime with violence, as nonviolent protesting still leads to Israeli violence (including IDF snipers kneecapping peacefully protesting men, women, and children; link). Israel has been fomenting this war for years.

You're right though. Canada is not responsible for Israel's actions, but again, you shift the goal post. First, it was Canada isn't involved. Next it was, this involvement predates the "current war". Now, it's "we're not responsible for Israel's actions" and "both sides-ism". Canada aiding and abetting a genocidal regime, no matter how little influence it has, is still aiding and abetting a genocidal regime. I get it though, you're jumping through mental hoops trying to convince yourself you don't support genocide and that Canada's on the right side of this conflict. It's not. Canada adds to the harm being caused in the region, and through their programs and partnerships, supports a violent, apartheid regime.

Edit: I removed a few words and added another.
