I will point out your sarcasm is unappreciated. We can conduct ourselves in a civil manner, no? Or are we still children incapable of polite debates? You're using sarcasm to prove your point, but you could prove it in other ways.
You are able to fix your eyesight and improve your living, be it with lazer eye surgery, glasses, or contacts. Blind humans have technology/seeing aid animals at their disposal. If you do/will/did involve yourself in the genepool, then your children would/do have bad eyesight. You can get them glasses, not a huge issue. Blind fish... what do they have or what can we give to them to help them? Nothing much really. We just have to try our best, stick them in small containers so they don't get lost in large tanks, feed them in the same spot at the same time of day so they learn how/where to get food, and keep their enviornment barren so they don't get caught in decor and die. Tell me you would breed any living creature at all knowing that might be the fate of their offspring.
Thank you very much for your genuine concern about my concern for the quality of the lives of my and other fish. It sounds like you think I am a hypocrite. Kudos to you, we are all hypocrites in one way or another

. Yes, bettas have slight difficulties, but they are still able to carry out their lives in a healthy fashion. May I point out like hm bettas, obese people (I know this might border on politically incorrect, but it helps prove my point) have issues moving around too, they're still able to live good lives (unless they are so morbidly obese they are confined to a wheelchair their entire lives, in which case I could compare them to a halfmoon with way too much finnage).
As for
If you want to look at it this way, you can. But, you too are "posturing" over the heavy finnage and bright colors of bettas, all the while you are dismissing the issue of albinism.
