sigh youre missing my point but that seems to be the entire theme of this thread with me and you, so im going to let it go....
No. You're missing the point. You keep looking at portions of my posts myopically for the sole purpose of debating and completely ignoring the point of them.
I can only make an answer so clunky, before I think it contains enough caveats to cover every irrelevant "What if...?" you can throw back at me.
My initial point, stripped to it's core, is that most of society's laws are common sense. There are practical, justifiable reasons for outlawing things like murder and theft that are beyond debate.
This is the post that led you to claim there was a justifiable comparison between the two:
Most (if not all) of these reports make the erroneous assumption that this behavior is normal. As if murder, porn addiction, or thievery are normal forms of behavior
Yes, relationships can cause harm, but there is no inherent harm caused by them, gay or straight. That was my point. A drug addiction almost inevitably leads to self-destruction, and it unfavorably leans towards harm to society (i.e. potential murders, thefts, car crashes, you name it).
