I'll go against the flow here (who, me? No way).

I flew a "trainer" precisely 2 flights. I found NUMEROUS reasons i didn't like it, and didn't fly it well. Jumped into an Electrostreak and a super stick, and couldn't have done it any better.

The advice you've received is sound and solid advice. Is it true that a VAST majority of new pilots have the most luck starting with a tradition high wing trainer? Absolutely it is. Are you "doomed to certain failure" (or, as you've been labeled here, simply 'wrong') if you start with something else? Absolutely not.

The FACT of the matter is that every individual is different. Sure...MOST people have success with a slow-to-respond, slow-flying, "stable" high wing trainer...but SOME people have success with a quicker, hotter, crisper airplane. Neither group is 'right or wrong', nobody is "better or worse"...we all just happen to be different.

I WILL say this though...ABSOLUTELY get yourself an instructor who will buddy box you. If you run into someone who simply refuses to teach you because they don't think it's possible to learn on Airplane X, find someone who's more open minded. Now, if that person tells you...AFTER FLYING WITH YOU...that you simply can't handle this plane yet, be willing to listen an accept that. But don't let ANYONE tell you it can't be done before you've even tried.

Some "alternatives" I've had good success with, either in my own progess or as an instructor:

The Hangar 9 Mustang PTS : Widely disliked around here, but I've had nothing but good luck teaching folks with it. Does it have quirks? Sure...every airplane (even a classic trainer) does...but there are those who simply refuse to accept a warbird as a trainer, and thus jump on these quirks as "flaws".

Hangar 9 40-sized Super Stick. Tone it down, and it's docile, slow, and forgiving. bring the servo travel back up later, and it's one of the funnest little "sticks-to-the-corners" beaters around. Don't let anyone kid you...there are GAZILLIONS of folks who learned to fly on one variant of the original Ugly Stick or another. It also has the advantage of being quite inexpensive, and EASILY repaired if dorked.

Sig Somethin Extra : A truly fun and capable airplane. Be aware that it is DEFINITELY hotter and quicker than a trainer. I certainly wouldn't expect MOST students to handle it, but I wouldn't automatically dismiss the idea either. I can show you a guy right now who not only learned to fly on one (one HE kit built), but did it without a buddy box...just passing the radio back and forth between him and his buddy who taught him.

Have fun with it....be willing listen when someone watches you try something and says "you can't do that"...but don't let anyone tell you "you can't do that" when you've never even tried.
