So far as I can tell, any civilians being killed in Gaza are, indeed, war crimes
This is my view as well.
the war crimes responsibility is entirely with Hamas.
I don't agree with "entirely". IDF is not doing enough to minimize civilian casualties. For example, blockade of delivery of humanitarian aid and ongoing famine in Gaza is fully on IDF. Another example is using kill zones, where IDF indiscriminately kills anyone moving. In such zones there isn't even an attempt to minimize civilian casualties, which is never OK.
But you don't, and won't - ever - talk about that, will you?
I absolutely will. Palestinians elected terrorist government that committed multiple war crimes and have a publicly stated goal of eradicating Israel. Israel is entitled to defend itself by retaliating proportionally. A lot of what happening right now in Gaza is well-deserved "find out" phase.
None of this changes the fact that IDF is also committing war crimes. Unless your view that there is no civilians in Palestine.
What about the October 7th attacks made Cancel Culture less of Left Wing thing?
October 7 was used as an excuse to conflate any criticism of Israel as antisemitism and call for censorship. For example, Ben Shapiro and DailyWire fired Candice Owens for criticizing Israel and US funding of IDF. The same Ben Shapiro that was famous for "Facts Don't Care About Your Feelings". Apparently, "yours" in his statement was not self-inclusive. Similarly, Dave Rubin cheered for EU laws banning pro-Palestine protests. These people were prominent in conservative circles for advocacy of free speech and opposition to Left's cancel culture only to perpetuate the same from the right.
Cancel culture is almost primarily a left wing thing.
After events of October 7, 2023 and IDF occupation of Gaza this is no longer true statement.
