#1- Gay Marriage y/n?

[5p carrier bag]

That's not a valid response. What evidence do you have that it is anything other than a choice?

Ignoring the countless studies showing it's not a choice, when have you ever met a person who woke up one day and decided "being straight is boring, I think I'll be gay!". I highly doubt you ever chose being attracted to women(or men) at some point in your life.

Don't give me that. How do you explain Bisexuals? Basically you're saying gay people are born with some kind of mutation? Is that it? Maybe some mutation of a gene deep down in the brain. I somehow find that highly unlikely, if it is not a choice then what is it?

Saying bisexuality proves being gay is a choice is like saying that hair colour is a choice because there's more than two types of hair colour out there.
Answer this question:when did you(assuming you are a straight male) choose to be sexually and/or romantically attracted to women? Not when did you start finding them attractive. When did you specifically decide "do I want to find men or women attractive". Can you change that decision tomorrow, and find people of the same gender attractive, and no longer find people of the opposite sex attractive?

What causes someone to be gay is still a great scientific question, while the gay gene is one theory, there are many other theories(most of which rooted in biological causes), one of the more accepted theories right now being down to hormonal balance in the womb, and how the mothers immune system reacts to a fetus. However, it's pretty much an undeniable scientific fact that being gay is not a choice.

It heavily influenced by the way you were raised and if you were educated properly on sexual relationships. Even so, it's not right if a child were to be raised from birth (presuming he was adopted either as a baby or very young) in a gay family. Imagine being raised by 2 dads, it's just not the way it was intended to be. The kid would almost certainly be bullied, it's perception of sexual relationship would be completely out of place.

Because we all know that heterosexual parents only raise heterosexual children!
"Even so, it's not right if a child were to be raised from birth in a gay family"
So you're saying that regardless of your logic, which is all "theoretically speaking"(which seems to me like this is all just something you've thought up in your head, rather than anything that's based on any sort of evidence, peoples experiences, or your own personal experience), gay families are wrong because you're against 2 dads. Are you against single parents, since that's not "the way it was intended to be"? Do you feel 2 dads or 2 mums would be wrong if it was just a pair of friends, or relatives raising the children, rather than partners? Do you feel these children being adopted by gay couples would be better spending most, if not the rest of their childhood growing up in an orphanage?
"The kid would almost certainly be bullied"
So you're saying that someone's prejudice of something based on it being seen as "unusual" should mean that we should base the law on that prejudice, hence keeping gay parents viewed as "unusual". Once upon a time, black people drinking from the same water fountain as white people would have been viewed in a similar way, and many people would have used the possibility of bullying(or worse) as a reason to keep the water fountains segregated.
