The fact is that "Texas Barbecue" originated in Texas. God knows where your version came from, but you should enjoy it all you want in your neck-of-the-woods.
What this writer misses, what all of these arguments miss, is that Kraft nor Arby's have any concept of regional authenticity, and tend toward bland and homogenous crap. The only GOOD ANYTHING is the LOCAL version. All else is crap no matter where you are.
That's why I think North-East-South-whatever Carolina BBQ is crap, and you think Texas BBQ is not the best, and we are both correct from a regional perspective!
And finally, this author is still an idiot.
