This is an Honest-To-God (since we're talking about religion) question, not intended to be sarcastic (although it might come off that way) but...
Does Joomla have the functionality you're looking for? It would seem that you really like that software very much, so it seems like it would be a good fit for you.
I think this apologist community here is smart enough to know that Tiki isn't for everybody and we don't try to ram it down people's throats, but we do like to try to address possible negative impression of the Tiki software/community.
I'm just an average joe, with some mid to high level technical knowledge. I help out here and participate because I want to, not because I feel I have to. I like Tiki, I like what it represents and overall I feel it's a great piece of software. It sounds like you feel the same way about Joomla, so you should feel free to express your passion. This isn't a middle finger salute telling you to go elsewhere, simply that you should embrace your passions, and unfortunately for us it seems Tiki isn't one of them. No hard feelings.
