If you read my post, and the study I linked, you will see that I was referring to an increase in the number of people willing to engage in same sex behavior.
Sexuality is much more complex than dividing people into heterosexuals & homosexuals. Sexual attraction is scattered along a continuum and for some people the selection of a sexual partner is a choice (about 50% of 18-24 year olds according to
this source).
My argument was that legislation (such as ssm) helps to change people's attitudes, and attitude helps to determine behavior.
From the Christian perspective, same sex behavior is immoral and therefore Christians should not support legislation & educational programs that contribute to an increase in immoral behavior.
The "Christian" perspective is to treat others as you would have
them treat you. There is no other
rational option.
We do have legislation that allows for people to close their
door and more rules that restrict search by authorities.
These laws contribute to the ability of same sex couples
to have relationships behind closed doors.
We allow unrelated people to live together in the same
dwelling....this list goes on and on with no discrimination
of race, ethnicity, sexual orientation, habits, dreams,
height, age, hobbies, color, religion, etc.
You suggest that these laws should be removed becasue they
allow for increases in what you mistakenly call immoral.
Mark 12:31 - Thou shalt love thy neighbour as thyself. There is none other commandment greater than these.
Luke 10:25-28
...do this, and you will live.
