For these types of threads, I usually upvote things that are actually hot takes with some justification or unique insight. People that post an extremely popular decision or just insult something that a lot of people see value in get downvoted. Mostly it’s moderately common takes or unusual opinions with no elaboration, so I don’t vote on those.
Milk in the US uses a different pasteurization technique the most of the rest of the world, so we need to keep it refrigerated while other places don’t until it’s opened.
