"Some" also consider that having handguns in your house can be detrimental to kids, should we outlaw guns as well?
By the way..."some" used to support miscegenation laws, did that make them right?
"Some" used to support Jim Crow laws, did that make them right?
You seemed to take the bait that the government could stop to blood related people from getting married/having kids because it would somehow intrude on your rights.
Then again 2 lesbians "father shopped" so that they could bias the odds at having deaf children (and got their evil wish). The government did not intrude in that wicked bit of child abuse.
