Form follows function in my mind. Whatever combination of parts presents the best gun for my intended purpose, at a price I'm willing to pay, is usually the one I'll pick!
I like the look of a nice walnut-stocked and blued rifle, but I also like the look of a new-age tactical rifle. Still, I don't buy guns for looks, I buy them for a purpose (whether that is hunting, target shooting, self-defense, work, etc).
As far as "tactical" is concerned, I am really tired of how toys are marketed on guns these days. Everything that goes on my guns has a purpose, and a reason for being there. These days I see a lot of mall ninja types who seem to think that you need to have 10lbs of SLC (scary looking crap) on a rifle to make it effective! Sadly, that attitude isn't just restricted to mall ninjas either... Some of the officers at my department have their guns so loaded down with useless B.S. that I'm amazed they can even manage to carry the thing in the field for more than ten minutes!
Of course, as someone already mentioned in this thread, "tactical" is also infiltrating the ranks of hunters these days. In some circles you'll practically be laughed at if you don't bring an uber-super-ultra magnum rifle for a deer hunt (though I think most old timers laugh at the crowd that subscribes to this philosophy). It also seems like you need to have a few thousand dollars in clothing to go elk hunting, though I've known a few old timers who still hunt in their jeans and flannel shirts (guess they didn't get the memo?).
So, to sum this all up, I guess I'm not tired of "tactical" stuff, I'm just tired of "tacticool" stuff. If it has a justifiable purpose, fine. If not, it isn't worth my time on either end of the equation!
