It's not about what racism is more important. Don't put words in my mouth. As if happens, in this moment anti Muslim hate is actually globally much more important than antisemitism but that has nothing to do with the point I'm making. Just talking about one thing doesn't mean it's more important than another thing. IMO it's quite meaningful to understand the various flavours of right-extremism, it explains a lot about the tensions between the various factions for example. There is currently substantial division on the right about whether to support Israel because they are killing Muslims or to hate them as well because they are Jews, and you may not care or want to think about that, it's perfectly valid, but the way it plays out will have serious political consequences and effects on the lives of many people
