Indeed, while this is a very reductionist position, I do agree that we all have different tastes, priorities and values, and we should date people who align with those.
We all have different views and opinions; point and case: of the vast array of majestic topics one could post about on Medium, how perplexed I was to see a post with a title like "My Partner Got Fat and That’s Not What I Signed Up for". But hey, each to their own, right?
Personally, I would much rather choose to date someone who gained weight, than the person who chooses to harshly judge or (internally or externally) shame them for it.
