Just be glad that you practice aikido. In my experience aikido people are more liberal with people that have practiced in different places. I did wing chun for a little while and my experience is that different teachers of this are rediculous about criticizing all your former teachers. They couldn't even agree about how they want to spell wing chun.
Martial arts are like little religions. Everyone has an epiphany and wants to become an evangelist of their truth. I'm quite guilty of this myself. We all are. My advise, and this is just me preaching, is to make whatever you want to learn your own. Don't worry about everyone else. If someone someday really likes what you do, maybe they'll ask you. Until then, keep working on you.
