Let's get started! First of all being "gay" doesn't mean your a guy, in fact it applies to all genders. Contrary to popular belief, this isn't known by everyone.
Let's get on to "real facts":
Fact 1: it's against God to be gay...
Analyze: Okay, so using religion's logic, God made love...love is one of the very few things that is considered completely pure. So while just looking at that fact, being gay is loving the same gender as your own, therefore it could not be the devil's work since it's a pure feeling.
Fact 2: It will cause the population to die out...
Analyze: The only reason to believe this fact, is that you would be living under a rock. Teen pregnancies are threw the roof! And it makes sense that we do not have issues with population deflation..if anything we currently have issues with population inflation. Due to this fact, people being gay would mean they would have to adopt, that means that all those children are in a loving home with a family; instead of in an orphanage dreaming of the chance of getting adopted.
Fact 3: If gays were to be accepted, that means it's "alright" or "promoted" to be gay.
Analyze: I kid you not, when I was looking for reasons why being gay is "wrong" this popped up! First of all being gay isn't a choice, meaning that just because people accept gays, doesn't mean there are going to be more. In fact, there has always been the same percentage of gays. They are just "coming out of the closet" more because the population is slowly realizing that you aren't "dammed to hell" if you are gay. So that's basically my summary on that point.
I think I summed everything up,so if any readers out there want to debate in the comments (which I will be monitoring and responding to) do it peacefully.
