I’m not attracted to your profile at all. But I’m a straight guy so what do you care.
I hate to say it but you are doing something wrong. No way to know from what you are giving us. Someone close to you knows. Ask them. I don’t think I am particularly attractive or special. I don’t have the ability to go into a bar and pick up who I want. But I have been reasonably successful in relationships. If I can do it anyone can. Maybe your expectations are too high? One of my acquaintances who has become old, bitter and alone complains constantly about the evils of women and why they won’t date a nice guy like him. Believe me it is obvious to all his friends.
If I had to guess from what you describe I could see you coming off as desparate or too needy. You seem to set your default position for women at love. Try for fun and see if love happens. I could be wrong about that but its the impression I get.
The whole hippy vegan green thing you are pushing on your profile will narrow your choices. But you do want someone you are compatible with so that might not be a bad thing.
But don’t be discouraged by lack of responses from online dating sites. If you get replies from 1 out of 10 you are doing fantastic. Its usually a lot less than that. And it takes only one.
