Taildraggers more dangerous - no - I dont think so... I learned to fly in a Piper L-4 (Cub) and got my PPL in such airplane at 17 of age. My son started to fly at age 13 with me, in a L-21C Super Cub, and he also got his PPL in that type of aircraft. As a knowledgeable pilot, I recommended to him to learn to fly in a taildragger first. A Super Cub will get you "out of troubles" much easier than any of the modern flying machines. You probably can land just about anywhere. And, if you landed there, you will be able to takeoff from that small piece of real estate. Not many planes can do that...
BelArgUSA- you're clearly a much more experienced pilot than me and as someone who learnt on tailwheels you probably don't see any difference between the two in terms of the likelihood of a landing accident- but in the modern GA enviroment, considering that most taildraggers are flown by people who (like me) started on nosewheels and have the majority of their hours on nosewheels I can't help thinking that a tailwheel aircraft is more likely to be involved in a landing accident than a nosewheel aircraft.
