The crucial difference is that the US is in no way supporting Iran but was and is heavily supporting Israel. So a protest in the US to stop that support is wortwhile. A protest to stop non-existent support is pointless.
You can still protest to signal support for usa to keep its hardline stance on Iran or to increase measures.
You can also protest to make sure the horrors aren't forgotten and to signal to those suffering in Iran that they aren't alone.
