I don't think we need to resort to bizarre conspiracy theories involving global manipulation and the like to understand this. It's very simple.
On the one hand, at its core, there is a community of people (the LGBTIQA community) whose self-understanding is now so radically different from what it used to be that they have come to a point of demanding that society change, in order to reduce the damage done by the fact that they don't fit well within social structures. (Note: the damage done by that is real; and can be measured in sobering statistics about suicide rates and the like).
On the other hand, there is a community of people who see such change as unnecessary and potentially damaging in a variety of ways. Not solely a Christian group, but more accurately a range of different groups who are concerned about those changes for a variety of reasons.
The fears and needs of these two groups are not easily going to be met at the same time; we are struggling, as a society, to work out the best way forward. What this vote has said is that we are no longer going to tolerate one group being made to pay the whole price (in terms of personal costliness) for that disjunction. I am not sure that that is entirely a bad thing.
As far as the Church goes, we need to remember that we have a mission, and it's not micro-managing either secular laws or our neighbours' bedroom habits. We have a gospel to proclaim, people to teach and nurture in the faith, and so on; and it would be a mistake for us now to get so distracted by this that we forget what we're supposed to be doing.
