Can someone give me an explanation for why Mike Cardwell, who lives in the UK, blocks Iranian IPs for “your decision to arm Russia with drones so that they can indiscriminately massacre civilians.” but does not block US or UK IPs for their decision to arm Israel?

The answer would seem to me to be racism – he values Ukrainian lives more than Palestinians and considers non-white citizens in non-democratic countries responsible for their country’s actions, but white citizens of democracies innocent.
