That doesn't make it normal.Homosexual acts are seen in the animal kingdom among many species so it's more likely that it's existed a lot longer than man since there was life before man appeared on the planet.
It's normal...just uncommon. Rather like being red haired or left handed.
I have to disagree on the left-handed part of that because it's not really uncommon. Approximately 30% of the population is left-handed.
Uhmmm--you can probably find stats that suggest 25% of the population is either Homosexual or Transgender(there is more of them than you think!!)
And?
He just argued that Homosexuality is as normal as being left handed.
