'You're on the Wrong Side of History!' - 3 Ways to Respond

I am thankful to God for Joseph - an atheist and LGBT friend that I met back when I resided in Ireland. Though we have a host of issues that we disagree over, he knows how to take it all in good stride and rarely makes a thoughtless argument or resorts to name calling.
Sadly, I have not experienced many people like Jo among those with whom I disagree - be they about God, LGBTism or other issues. This morning I awoke to yet another message gernaded through social media at yours truly. The ill-defined term ‘homophobic’ was the – rather uncreative – pejorative of choice. Why did they toss this term at cuddly, lovable ol’ me? For for the unfashionable crime of holding to the Biblical (and historical) idea of marriage being something that can only exist between a man and a woman.
One of the popular soundbites being chanted in debates at the moment is the accusation that one ‘is on the wrong side of history’. Now we hear this used in a few different contexts – not just at those who dare to publicly question current LGBT orthodoxy. The one who has this faux argument shot at them is apparently supposed to shudder and recoil in defensive horror. Though ignoring it is always a fair option, some of you may wonder how to respond. Three ways come to mind:
The first is the pious response. Simply reply that being on the wrong side of history doesn’t particularly bother you. We are all going to give an account of our lives to the Creator – not to a history book. In the light of Eternity, being a part of the intellectual pezzonovantes of the day simply isn’t a big priority. And Lewis pointed out, anything that’s not eternal is eternally irrelevant.
The second is the cheeky response. Simply say that you’re not on the wrong side of history. In the case of the gay ‘marriage’ debate, those who understand that a marriage is fundamentally something between a man and a woman are on the same side of 99% of human history. Even the Romans and Greeks – who practiced sodomy with great enthusiasm – still maintained that marriage was between a man and a woman. (More Here). What people mean when they talk about being on the wrong side of history is being on the wrong side of their imagined future.
Lastly, we have the empathetic response. Simply point out that we are all on the wrong side of history - at least in how they mean the phrase. By saying, ‘You’re on the wrong side of history’ the pro-gay ‘marriage’ crew mean that younger generations increasingly embrace this part of LGBT ideology. Therefore people who don’t embrace this new view of sexuality and gender are on the wrong side of a growing social trend – and therefore of history itself. Simply reply:
But aren’t there some growing social trends that you are on the wrong side of? Nationalism is growing. What about the wealth gap between the rich and the poor? That’s increasing and showing no signs of letting up anytime soon. If you oppose nationalism or huge wealth gaps between the very rich and the poor, then you’re also on the wrong side of history – at least for the time being.
If the person you’re discussing with is someone like Jo - one who is at least semi-reasonable, thoughtful and open, - then I’ve found the last answer the most disarming and fruitful in paving the way for further respectful discussion.
