Narrative:
First officer was flying. We were cleared for visual approach 17L. Approach to 17L crosses runway 13L. ATR-72 was cleared for takeoff on 13L with us on short final, runway 17L. Tower did point out mutual traffic. ATR took longer than expected to start to roll and accelerated slowly. First officer elected not to go around and I did not either. (Wish now I had!) we got too close to ATR for comfort, and passed through its wake turbulence. After landing, I told ATC that spacing was too close and we encountered wake turbulence. Tower said: '...from an ATR!!' I did not appreciate that remark and called tower on phone. The supervisor knew all about this incident. Basically all this was my fault, because we were on visual approach and to maintain our own separation. (Looks good on paper....but in the air it is a little different!) supervisor was defensive, I got defensive, too. Supervisor told me that tower controller was surprised to hear an ATR has wake turbulence (???) and was not trying to be a smart aleck. (I am not buying it...) I should have ordered a 'go around' for safety. I let myself get 'boxed' in.

Title: ATCT LCL CTLR AT DFW QUESTIONS PLT'S COMPLAINT ON WAKE TURBULENCE BTWN AN ATR-72 DEPARTING RWY 13L AND AN E-145 LNDG ON RWY 17L.
Narrative: FO WAS FLYING. WE WERE CLRED FOR VISUAL APCH 17L. APCH TO 17L CROSSES RWY 13L. ATR-72 WAS CLRED FOR TKOF ON 13L WITH US ON SHORT FINAL, RWY 17L. TWR DID POINT OUT MUTUAL TFC. ATR TOOK LONGER THAN EXPECTED TO START TO ROLL AND ACCELERATED SLOWLY. FO ELECTED NOT TO GO AROUND AND I DID NOT EITHER. (WISH NOW I HAD!) WE GOT TOO CLOSE TO ATR FOR COMFORT, AND PASSED THROUGH ITS WAKE TURBULENCE. AFTER LNDG, I TOLD ATC THAT SPACING WAS TOO CLOSE AND WE ENCOUNTERED WAKE TURBULENCE. TWR SAID: '...FROM AN ATR!!' I DID NOT APPRECIATE THAT REMARK AND CALLED TWR ON PHONE. THE SUPVR KNEW ALL ABOUT THIS INCIDENT. BASICALLY ALL THIS WAS MY FAULT, BECAUSE WE WERE ON VISUAL APCH AND TO MAINTAIN OUR OWN SEPARATION. (LOOKS GOOD ON PAPER....BUT IN THE AIR IT IS A LITTLE DIFFERENT!) SUPVR WAS DEFENSIVE, I GOT DEFENSIVE, TOO. SUPVR TOLD ME THAT TWR CTLR WAS SURPRISED TO HEAR AN ATR HAS WAKE TURBULENCE (???) AND WAS NOT TRYING TO BE A SMART ALECK. (I AM NOT BUYING IT...) I SHOULD HAVE ORDERED A 'GAR' FOR SAFETY. I LET MYSELF GET 'BOXED' IN.
