It’s not that Liam or any other celebrity is more important than anybody else. It’s that they are more widely known.

That doesn’t make them less worthy of empathy, just less well known.
I buy my dog a particular brand of dog treat because the damn things smell SO GOOD. Literally like a bakery. I’ve never eaten one, but I take a big whiff of the bag every time it’s open.
