Idk I feel like I've been around the block and feel there are a decent amount of annoyances everyone should be able to agree on. For example:

-The dating market tells you what you are worth. If a 5 has never been interested in you, chances are you're not a 5. Of course, this isn't only about looks. It's about your prospects and personality as well. So many issues in the dating world happen because average women blow off average men, without realizing they are also average, or grossly obese, weird man only feel they can go after models they have nothing in common with. Unfortunately, a lot of you are worse in more ways than you think.

-People in similar socioeconomic classes stick together. This is just a fact. A lot of the idea that women are income-hunting is just not true. https://www.nber.org/digest/may14/assortative-mating-and-income-inequality

In other words, wealthy men from Harvard don't take random McDonalds employees seriously, for the most part. If I grew up going on luxurious vacations everywhere, why would I marry someone who has never left the state? What would we have in common?

-Hating the gender you want to date is bad. It's bad karma and just weird. Healthy relationships don't come from this

-Being overly possessive about someone's sexual past is bad. It screams insecurity and regressive views. Some people can tolerate that. I cannot.
