Anyone who wants to generally monologue can find their way to the "World of Other Stuff" or "Rant, Rave, & Misbehave" section. There are several ongoing threads which are ideal for such themes.
As far as validifying/apologetics of Pastafarianism to others, I can think of a few general approaches:
Point out that religion should be FUN. It should connect people socially, emotionally, and in ideas. It should help people learn how to live in peace with the world. It helps if the religion has some scheduled/cyclical observances or holidays to help people rejuvenate their love of life and peaceful growth, encouraging members to continue their life-path. If some other religion does not meet these standards, then clearly it is inferior, but CotFSM meets them all. (The FUN clause is important, for it was common in almost all ancient religions and largely absent from many modern ones.)
Alternatively, you could invite them into the forums to browse and see what is really here. If they won't even do that, they aren't serious about knowing the truth, so there's no point in wasting your time on them. Many great social and spiritual issues are discussed here, in our grand cathedral of the internet, which members can access any time they sign on for personal support and interaction around the world, without an appointment. This is inherently superior to a single or limited buildings that are only available in limited timespace events.
If someone is looking for meaty dialogue, let them check out the "Serious Discussion" section, but genuine spiritual/religious stuff comes up all over the forum. For example, I just posted a 4-part metaphorical analysis of the Aspects of FSM in the "Indocrinating Children" thread that might be of interest to someone looking for ways to see FSM as a means of contemplating reality. Most importantly, our dialogues do not represent official dogma, so they can be taken as they are useful and meaningful to each individual without requiring wars or genocides to enforce them. This is an element of a superior religion, that it can grow with each person and generation instead of stagnating in some long-past century. Other "major" religions would do well to learn from us.
I think the more important question is: "How can other major religions validate themselves in light of the living traditions and advantages of Pastafarianism?"
In case you didn't realize it, I DO have a sense of humor. How about you?
