Re: How to speak to norms
The first step, in my opinion ofcourse, would be to give the non-kin or unawakened enough respect to refrain from using derogatory slang words to refer to them. (Norms, hoomans, mundanes, muggles, or anything of that sort is just plain disrespectful.)
Secondly, be a rational, intelligent, and reasonable human being, not only in how you present your beliefs but also towards the person you're speaking with.
Start small (like has been mentioned) with beliefs regarding reincarnation, soul, energy, etcetera. The base, foundation, for your beliefs. For me, this would come out something like this (after leading the conversation towards general spiritual/religious beliefs to start with): "Well, personally, I choose to believe in the concept of reincarnation. From my perspective it just seems natural for the soul to be recycled and re-used just like everything else in nature."
From which you can introduce the concept that it's not neccicarilly bound to one species. Taking the time to mention that this is just how you see it ofcourse.
After all, none of our beliefs can be proven at all anyways.
But more importantly than Anything else...
Be ready and willing to answer questions!
If you are the sort of person who equates being question with being attacked, then you'll have to get over that before you can present your beliefs in an reasonable, intelligent and rational manner. Our beliefs are not all that "out there" but they are uncommon and as such they Will be questioned!
