1) Do you think it should be illegal completely?
I am certain that making it illegal would hurt the research that depends on experiments.
That being said, experiments on babies could result in negative consequences. It is not the case where we know that "if we do A, then B will happen".
Its an unknown area that carries lots of good things in case it is successful, and lots of bad things in case it isnt.
2) Do you think it should only be legal to prevent life threatening diseases?
To this, I would say if chance of death is high, and if modification of genes can make that chance lower, it would seem fine to accept it.
3) Do you think it should also be legal to prevent major learning, developmental, immune disorders?
Disorders usually make life difficult for people who have them.
To 2) and 3) I would ask at what scale does modification need to be done to achieve success? Obviously, genetically modifying every person could have horrible consequences. As a specie, we cant afford to threat our existence with everything new we can think of.
4) Do you think it should also be legal for prevention of minor allergies, asthma, etc?
Asthma was horrible to deal with in the past. Today, they have some medication that helps a lot. Allergies too are mostly managed.
However, if it can be correctly detected who will have these and who wont, it seems logical to do modification.
5) Do you think it should also be legal for convenient purposes? (For example if my parents made it that I didn’t grow bum fluff, I’d be so grateful).
I would want to be careful with how far this goes. In this case, it would be on a mass scale. We should not do it on a mass scale until we confirm it's safe on a small scale.
6) Do you think it should also be legal for cosmetic purposes such as eye, hair, maybe even skin colour, etc?
This does carry some potential. No matter how subjective it is, if a person is ugly, then he/she is likely to have a worse life.
7) Do you think it should also be legal for cognitive/biological enhancement such as stronger than average bones, easier to build muscle, easier to lose weight, greater intelligence, etc.
Greater intelligence is what I would support.
Stronger bones maybe.
Muscles might not be a good idea. You need to eat a lot more food if you have greater muscle mass. Plus, muscles are not that helpful in today's society, and wont be in future society where labor is abolished.
Also, muscles vs intellect improvement, I would choose intellect.
A no holds barred approach, anything goes. If you want them to have a greater number of arms, eyes, etc, or you want to splice animal DNA with them
This would be taking it too far. Moral problems are reduced if you dont consider semen as person. However, even those that dont consider semen as person would be outraged if we started giving birth to werewolves.
