Is the analogy really that hard to understand, or are you being deliberately obtuse?
If I say, 'I do not have a faith, in your or any other God', you seem to reply 'Well, that's a faith too.' How, precisely, is that different from my saying 'I do not participate in any sports' and your replying, 'Well, not participating is your sport.'?
Unless you really don't know the difference between 'belief' and 'faith', you're merely juggling semantics, using words like the great philological authority Humpty Dumpty, to make them mean what you'd like them to. That can be fun, but is basically a form of mental masturbation: something you really shouldn't indulge in publically.
