The implication here, of course, is that anyone who cares about children being murdered in Iran is coming from a position of privilege. I must just have such an easy fucking life that I have time to care about other people! I guess I don't have any problems, I'm not working hard manual labor every day or drowning in debt or living in constant terror that the wave of trans hate is going to get me killed. I guess my problems aren't real and I'm not forced to sell plasma to hang on by my fucking fingernails, my life must be great, and that's why I have time to care.
The reality, of course, is that the most privileged people care about Iran the least. They care about gas prices because they drive oversized vehicles, because they can afford to own huge trucks and SUVs.
