I like the way you think sir!
Without making any conclusions based on your thought experiment I would predict that should someone test your hypothesis, the police would likely enforce the trespass on the grounds that your claim of religious protection would have to be heard in civil court.
What I suggest to initiate this test would be to make your religious views known publicly in various forums, Facebook, a bumper sticker, t-shirt and allow enough time to pass for people your interact with regularly to have a fond recollection of your expressed religious views. Visit a public place known to be hostile to your religious expression. You must then document (audio/video) their infringement upon your status as a member of a protected class and initiate a civil action on those grounds. From there you must resist the temptation to accept a settlement (it will not admit any liability), a judge/jury must render a judgement, you must also demonstrate, on cross examination by the plaintiff, a thorough understanding of the beliefs in which you claim to hold that are germane to your faith; i.e. a thorough knowledge of your religious doctrine, not just one obscure quote from a key historical figure.
It's not over, you haven't won by any stretch of the imagination. Should you be victorious in your civil action the plaintiff will almost certainly appeal all the way to the state supreme court. This will be the decision that really matters, and it will cost you an arm and three legs to fallow this through.
