That’s pretty much the extent of the “both sides bad” argument, no real substance. It’s a cowardly way of siding with the opressor. I think it’s also based heavily on ignorance, as if both sides have equal power and they could just have a gentleman’s agreement to duel at midday and settle it. That totally ignores both reality and history, but I get it, it makes one feel he has the moral high ground without actually doing anything or even taking a side.
