Then it's autism. Not the fact, that they are not "loving enough" as a person. If you say women don't want to date autistic spastics, I'm not gonna object. But being autistic also isn't their fault.
I know a guy from school, he must be somewhere on the spectrum. He had his first girlfriend around the age of 20, and he met her at work. She basically hit on him and he just had to accept her advances. She seduced him. Jntroduced him to things like fisting. Later turned out she was raped by her father as a kid and she literally screwed a mechanic, when my friend wasn't home. He came home, caught her. Guy got dressed and left, she claimed it was rape. The guy kept coming to their house to work on whatever he was working on until he was finished. My friend didn't do shit about it. Short time after that she left him, got into prostitution and checked into a psychiatric hospital.
My friend hasn't had a girlfriend since and he has low confidence, suffers from depression and has trouble meeting new people, especially girls. He's one of the nicest people I have ever met. He's reliable, loyal and kind. In terms of looks, he would even be doing pretty well, he's pretty tall and still has a full head of hair. Some women probably consider him somewhat handsome.
Now if you tell me, life's tough, life's not fair, he's born somewhat autistic so women are just not gonna line up to date him, that's ok. That's a realistic approach. But don't tell me "just be a loving person". That's saying that if you don't have success with women, that's because you just not compassionate enough and that's just bullshit. If you have any experience with people, men, women and their relationships with one another, you know that's bullshit.
