Read a tweet today about why Gen Z men are not "manning up" and cold approaching women. It's obviously the fear of getting your life ruined, not the fear of rejection.
This is established fact for virtually anyone who's ever thought about the subject (besides NPCs).
But my thought is even if you somehow took away the risk of ruining your life, there are a lot of problems with expecting men to find relationships by walking into the buzzsaw of cold approaches over and over. First of all, it kind of hurts to get turned down based on your physical appearance, and the appearance of 80% of men is inadequate on its own. You can make up for that with banter and flirting. But is it realistic to expect every man, or even most men, to develop the level of game needed to pick up girls off the street?
Second, most attractive women you see on the street already have a boyfriend. Not a meme boyfriend, an actual dude. Now it is true that if you're Timothee Chalamet you can probably turn half of those women into cheating hoes, but why would you want to given that you're going for a serious relationship? In the end it's just very awkward for both parties to go through the script again and again. "Sorry, I have a boyfriend." [forced smile] "Oh, my bad sorry"
In the past women were somewhat more likely to take cold approaches as a compliment. Disclaimer: somewhat more likely. Today the infinite choice of online dating has more than filled women's thirst to be admired, so getting approached in public mostly makes them annoyed for the same reason that most people prefer to be emailed rather than called.
There is a way for guys who aren't male models to be attractive to women: get to know them in a mutual community so their appreciation of your positive features overcomes the "ick" and "he's not a kpop boy band member" factors that they initially notice. People can also figure out who's in a relationship and who's looking without embarrassing themselves. This form of courtship, coincidentally, has been attacked by each successive sexual revolution.
I'm generalizing in several places, but I doubt that most relationships are going to happen through cold approach in a healthy society, whether that's in person or on a Jewish dating app.
The other thing people tend to forget: majority of women you cold approach are already alpha widowed.
Rollo did an excellent video on this. Any woman who has already rode the carousel to any extent on dating apps is already a washed out and ran-through wench. I know a lot of guys don't want to think of it this way or accept this harsh reality, but it's true.
They found that the average 19-year-old girl these days has a bodycount equivalent to a 54-year-old woman from the previous generation. And I'm sure that's a conservative figure given that most women now lie about their bodycount because they know men find it to be a huge turnoff.
So even IF you opt to cold approach, you're either cold-approaching someone who -- as you mentioned -- is already in a relationship, and either not willing to give you the time of day or willing to cheat if you fit the Chad/Tyrone stereotype, or she's already ran-through and alpha widowed and you'll always be a beta-bux provider while she still dreams of being with the Chad/Tyrone who made her walk funny all those years ago.
Unfortunately it's a lose-lose situation for most guys unless you are cold-approaching in an absolutely traditional, highly conservative, middle-of-nowhere place where every young woman there hasn't already become the town bicycle before they even get their first job.
