I talked to a boomer fox news watcher recently, and apparently the current party line is that since the US firebombed dresden, what Israel is doing to Gaza is justified. The US even bombed white europeans, so how can you criticize them for killing middle-easterners?
IE, nothing wrong with murdering civilians as long as the US did it first, and to criticize Israel for doing what the US already did is unpatriotic, and the protesters have no right to protest this genocide.
At least the US right is honest about their values, and make no justifications or apologies for civilian murder.
