I'm sorry, but that's complete BS. Playing any type of guitar does not limit you to a specific style of play - you can play any style you want on any type of guitar. Some advanced techniques and progressions (i.e, solos or conversly fingerstyle) will be more comfortable on specific guitar types, but there's no technical limitation from playing anything on every guitar type. Those distinctions are mostly meaningless to beginners who will be mostly playing simple chords and melodies (to which I would say, a classical guitar is the most comfortable form factor).
