I go to help my wife (I enjoy looking around). We take my mother inlaw because she has macular degeneration and can't see that well to drive. The kids like to come for a slice of pizza or a hotdog and we enjoy being with them.
No one should be offended because you enjoy different things in life than they do.
Perhaps if they somehow first convince themselves that the “whole world is suffering” because someone has a vehicle which can fit their nuclear family in it, and second convince themselves that condescending you on a message forum is an appropriate way to somehow lessen that behavior...
But no, that comment is just out of order.
I saw an interesting article today “Joe Rogan World vs NPR World” [1] which describes our current political environment, and it seems to me this type of interaction is emblematic of it.
I'm sorry that offends you.
