We haven't empirically test the gun culture split recently. I'd bet folks are on it.
However, not ignoring the past research is foolish. My point is that recently we've heard a great number of folks come forward as prohunting and then for gun control.
There have been massive efforts to 'normalize' EBRs - calling them modern sporting rifles, etc.
Will that work? Did it work for a bit but reversed in some minds by Sandy Hook - we don't know.
Is there overlap of hunter/SD - yes - my skeet teacher was a progun in my sense fellow. But are all?
We shall see.
