You're hurting your chances of not reproducing a lot more by having a negative attitude and zero confidence. As hard as it may be you need to try to get it into your head that there are genuine good people out there who don't care about a treatable skin condition.
Not really. I know someone in real life who has zero confidence and when he had acne no girls wanted him. He cleared up after puberty and know he has no problem in that regard even though he still has no confidence and has a bland personality. Personality and confidence didn't change but his looks did and that's the only thing that mattered enough to solve his problem.
You bring up other negative physical traits that people have. Well, people with acne can have those terrible traits in addition to acne, which makes them completely screwed. If someone is ugly to begin with, has a mental illness and acne then they're pretty much screwed.
And not everyone's acne is treatable.
That's some pretty fallacious logic you've got going on there. Making a generalization based on one person you knew is foolish to begin with, paired with the fact that correlation doesn't equal causation. Maybe girls are more likely to approach guys after puberty or maybe he entered college which gave him an environment which facilitated male/female romantic interaction. You can't argue that it was solely because his acne cleared up.
Some people are more flawed than others, you're absolutely right. But that still doesn't logically explain why people with acne shouldn't reproduce. If a woman with a gigantic nose AND oddly shaped eyes is married to a man with thyroid disease and hideous eyebrows, should they abstain from having children? There are people with far worse things than acne who are reproducing as we speak and not thinking twice.
Yes, there is a ridiculously small percentage of people who have not responded to multiple rounds of the best acne treatment in existence (Accutane). Even so, most undesirable features aren't "treatable" in the sense that they cannot be changed or fixed.
It's not any worse "logic" that someone using a cop out response by minimalizing the importance of looks and giving the old "confidence and self-esteem" cliche. You can sure argue that when someone's looks improve than their outcome improves despite personality or other factors. If someone has hideous acne for several years and then it clears up then that that can absolutely be a sole factor in improving thier circumstances and it's flawled logic to think otherwise.
Also, we are more flawed and uglier looking than the average people. It's true. People say acne is common but I rarely see any adults with severe acne. Most adults that I see in person have clear skin and can eat McDonalds and other shitty foods everyday. It's not normal or desirable to have red markings all of your body and it's depressing to even look in the mirror, especially when you realize your skin used to be clear and that it never will be again despite years of treatments.
I agree with that looks matter. It might even be the only thing that matters when it comes to relationships, but that is not our fault. The culture brainwashes people to focus on looks via the beauty industry, the porn industry, etc.
