This is another odd phenomenon on the left: taking ‘offense’ on behalf of others who may not even know, care or object to the thought or deed. PC, thoughtcrime, etc.
What if Sam saw humor in it and even approved? Do the thought police still prosecute if the target is OK with it?
Sam is not a person to the left, he is a tool to further the cause. He will be treated well while he is still useful and discarded or even vilified when he is not. If Sam ever tried to put a stop to the leftist bile spewed in his name they would turn on him in a heartbeat.
