I think at this point its just a preference. I think the only people you see wanting specific things like height, money, weight, or others things are generally bad people. I know that some people want specific things out of their partner, and i understand that. But trying to force someone into something their not is just a dating taboo. Cause it only creates toxicity in the relationship. I think why people are like this now is that they are able to swipe and choose from a group of people at whatever time they want, and whenever they want. With Tinder and other dating apps at an all time high, people can be picky because there are so many people out there who are either horny or want a relationship. Making people take relationships as a joke, and only date people they like but will never bargain with their date. Cause if he/she wants something else or wants to fix something, that person can immediately leave and find someone with the exact same characteristics in less than an hour. So just don't interact with people you know who do that, it'll only hurt you. And I know it"ll be hard to find someone who isn't like that, but it's more rewarding because that person will love you for who you are, not what you have,
