Sam Smith came out gay when He was 10 yrs old, but who gives a shit?

Sam Smith said, “I am a gay man who came out when I was 10 years old”

The question is, how can a 10 yr old come out gay? Come out doing what? A normal 10 year old is not engaging the opposite sex and really has no interest in either sex. What kind of parents let their 10 year old “come out”? This is absolutely child abuse. Gay or not Gay, a child of 10 years old cannot decide on a color of His bike, much less His/Her sexuality.
