First of all, tolerance and pluralism are incredibly important; the plurality of Pagan traditions is one of that movement's great strengths, and tolerance should go beyond mere acceptance and extend to being respectful.
However, I also think there's a value to honest critique. I believe that the exchange of ideas requires critical evaluation of those ideas. Too often, I think the Pagan community resists this kind of discussion - which is the heart of theology, frankly - and dismisses it.
For example, someone who tells you are too "fluffy" is a jerk and should be ignored; but someone who tells you you're reinventing the wheel is potentially offering helpful information. If they know of structures or ideas that are similar to yours, they want to make sure you're aware of them; you may be able to learn from them, join forces with them, or at least bester distinguish what makes your ideas different.
Contrary to your illustration, I think tolerance has little to do with accepting. I think it is about respect. There are priests and magicians whose ideas I believe are flatly wrong - but I respect them, including using only respectful language about them, and we can hang out and be part of a community together.
@altmagic I would think that respect is part of acceptance. You may or may not. In regards to the idea that the comment reinventing the wheel is an honest critique, I have found in my own experience that it has been used to discourage creativity and experimentation. When I first started sharing my ideas around pop culture magic, the people who told me I was reinventing the wheel were in no way respectful about it, or in my opinion offering an honest critique. Beyond making that statement, they had nothing substantive to offer. They seemed more bent on discouraging creativity than anything else. An honest critique doesn't need a cliche, and can be argued in a respectful manner, but when I hear that I or someone is reinventing the wheel, what I hear is a petty insult offered by someone who has nothing more to offer than that.
I think it can go either way. I found it helpful though challenging to listen to people shoot off their opinions of my temple and teachings, when I was a temple priest.
@altmagic It can be very helpful. I can accept a person's choice of belief and still offer a respectful critique of the practices that are associated with the belief.
