OK, I've had a biscuit & calmed down a bit. 
OP as I said before you are welcome to post what ever you like. You and your family are, of course, completely entitled to take a view and have feelings about the decision your sister nation is making.
I too hold my identity as key to my sense of self, I get as misty eyed at Caledonia as the next Scot. But I truly believe that sentimentality has very little debate in this decision.
I'm not voting yes for some tartan whisky flavour shortbread version of Scotland. I'm voting yes in a fight for my country's future.
I'm sorry if a 'yes' outcome will make your DH a bit sad, but he'll still be half Scottish, your wee lad will still be able to be proud of his Scottish roots. There's only 5 million of us, we'll welcome pretty much anyone who wants to claim us as kin. Independence doesn't change that.
If your DH is proud of his Scots heritage he needs to look past some trite sentimental notion of us as a pretty wee place with kilts and midges and think about who we are.
We are fierce, and brave, and smart. We have been fighting for our land since before the Romans put up a wall. We have been down trodden and still we stand up again and again. As part of the UK over the last several hundred years we've contributed soldiers, politicians, scientists, engineers, scholars, poets and artists not to mention our bounteous natural resources. We've punch well above our weight on the world stage let alone on in the UK.
We just want a chance to do thing our own way. Make decisions for our own children. Take any decision that doesn't get outweighed by someone bigger than us.
We are fierce and brave and smart but they're telling us that we are too small and that we should be scared and that we don't understand the decision we are taking.
If your husband is sad, he should be sad about that. I hope you see why a cute picture doesn't sway me.
