Some people don't like sweets with their acids/savory foods. Claiming it's an argument over traditional pizza is a bit overkill.

How often are the same people as vociferous about disliking pork chops & apple sauce, chinese bbq, etc. ?

It's seems a pretty silly thing to get worked up about. There are vastly more egregious slights to the good name of pizza in nearly every american frozen food aisle, after all.
