I don’t support you to donate the sperm.
#1 It’s a tragedy for a child to be born in a single family.
#2 To raise a kid needs a lot of work and it’s not bearable to a single parent.
#3 A kid is raised in a special family will have unusual experience and negative atmosphere will impact all his/her life.
#4 A kid who live with two loving parents would be the most happy kid regardless what kind of achievement he/she has.
Don’t harm a kid since he /she has no ability to grow healthy by him/herself.
