Define being a 'real footballer'... Kids going out for a kickabout is 'playing football' (practising techniques etc.) and if they also play for a team (at any level) they're still playing football, with a competitive element.
Exactly the same with trials really, I go out 'for a bounce' just messing about and practising techniques, I used to compete (don't anymore) but I still call myself a trials rider, what else could I be bouncing around on a silly low geared bike?!
Your (lack of) logic is really quite amazing.
