It’s easy when you’re an obscure band to bellow “kill your local MP” or bray “up Hamas, up Hezbollah”.

Yeah, pretty much. Very few people would argue against stopping killing Gazan civilians (even if they are not willing to back the measures that would result in that, like applying real presure to Israel), that makes it a fairly apolictial thing to say. Advocating killing MPs or supporting Iranian proxies is certainly a lot more contencious.
