Simply not true. Some Males do not have this impulse, some Females also do not have this impulse. We call those people Homosexuals.
You are arguing from a pre-supposition of nonsensical positions assuming Nature as an Entity with Intent. No such thing exists except for in your mind.
Whether one is born with a Penis or a Vagina doesn't determine their Sexuality.
Youre right, we do call those people homosexuals. Whats your point? we arent arguing what being a homosexual is called, we are arguing if its right or not. I am saying that the only reason any of us are even here right now is because nature has hard wired just about every living creature on the planet to actively seek out, and mate with a member of the opposite sex. Nature is not an entity, and it has no intent, its just a term that easily describes the instinct and goal for all living creatures.
Homosexuality is biologically wrong, that is an absolutely factual statement.
