Well, that's a glib remark if I've ever heard one.
"Whataboutism" - so that's.. said to people who tiresomely derail discussion of seriously wrongdoing with their pat diagnosis and dismiss the original topic as naive. Unfortunately you have done that same thing by using the word.
I get why it's useful to have a name for the phenomenon, but there's nothing commendable about the way you used it, it came across sounding like a jerk who thinks they're superior. And made me wonder about what you "want to tell us".
edit: Could the downvoters explain why? Thanks. I tried to say something substantive, I thought successfully. (joosters, I totally agree)
IMO the person they were replying to sounded superior.
There will always be a more important issue than the one being discussed. (in the eyes of someone, at least). That's no reason to prevent talking about anything else.
