Everyone has a preference, and nobody likes talking to someone and finding out later that the person they thought met their preference actually doesn’t.
Then they’re put in a position where they feel like an asshole if they stop talking to the person over their body type, or they have to try and go against their preferences to be with the person anyway, which usually doesn’t go well for either person.
Even just one full body pic on every profile could save a lot of hurt imo
Edit: this includes people preferring skinny, people preferring fat, people who have a preference on breast size, height, whatever can be found in a full body photo. Not a fat shaming thing.
