...have the Gangrel left the Camarilla

If we're going by current timeline (the RP is set in 2017), then yes, the Gangrel have long split from the Cam since I believe that happened at the turn of the 21st Century. That being said, you can't assume every clan member has, but it's also safe to say that they would probably appear to other Gangrel as "traitors".
