Bishop Faure is not under discussion:
An American District website is the precise subject, and I will bet you $100 that, if I email Bishop Zendejas (with you CC'd in) right now and propose designing and maintaining a website for the American SAJM (which would include Mass locations, times, and contact information for all SAJM American District venues and events), he will have some reason (such as those you previously mentioned) for not wanting me to do it.
Do you doubt that?
I'm not a betting man, but why not try it?
I don't see why each chapel couldn't have a coordinator who checks a public GMAIL address. The coordinator could even serve God by giving out his phone number, so prospective parishioners could call. I do that here. Yes, it's volunteer work. But it's for God and nobody else, so it's all good.
You do need a "Grease trap" to catch all the gunk before it enters the main pipes. That's why you have a contact phone number/e-mail. A new parishioner should at least have to call and give their name, before getting the address for the place. If they want to show up anonymously without having to talk to anyone -- they are either a thief or a troll/heckler/troublemaker.
If they can't work up the courage to make a phone call, they will probably go into hives being in public (even just 12 parishioners) anyhow.
I'm sorry, but Trad chapels aren't Wal-mart. We have to acknowledge that reality. A retail store and a garage chapel are two very different realities. Usually chapels involve private homes, for starters. Trad chapels involve strong beliefs, strong opinions, strong emotions, and can set one person (an enemy) on a focused mission or quest to destroy. Wal-mart doesn't have to deal with this. If someone was trying to break things in the store, they could call the cops. There's no law against heckling, talking bad about a priest, or reporting to management that a priest's superior is a h0Ɩ0cαųst denier.
