Chuks,
I see that after the FlyAfricans did not agree with you, you had to give PPRuNe a try. I don't think that people would think that John Travolta is an airline captain. Even if they did, I don't think that it has any influence on me or my status as an airline captain. If your four bars are so important to you that the fact that JT wears them causes you to whinge on multiple aviation forums, then I suggest some professional help.
If on the other hand your problem is with Scientology (which I suspect is the real reason), then I suggest you take this fight to some religious forum where someone might care. Pilots come in all colours, shapes, sizes and religious beliefs. Even agnostics or atheists can become airline captains.....
John Travolta wears four stripes on a Qantas uniform as an actor who is a goodwill ambassador for Qantas. Take your fight up with them. We actually don't care.
