"Old fashioned" opinions or having an opinion in general. People nowadays think being progressive and open minded means being okay with everything and homogenizing. It's like no one is allowed to have their own opinions anymore or else you're "judgey". When IMO being open minded means understanding that people have different opinions because of their experiences.

Especially when it's relationship related Reddit will be quick to call someone a bitch or controlling without thinking that there's more to the story, that maybe this dynamic works for that couple, or maybe there's an understanding or compromise between the couple. Things like "I don't want my partner going to strip clubs" "We let eachother go through our social media" etc. If it works for other people, makes them happy, and doesn't hurt anyone then leave them alone.

It's IRL too. I can't leave a room where people are watching a music video of girls running around half naked without being called a prude or can't decide to not watch a popular show without someone saying, "apparently she doesn't want to watch stuff that's good".
