I typically don't really discuss Heathenry with anyone who isn't either a Heathen or a white who seems receptive to the ideas or knowledgeable about them. I'll talk about it with white Christians (redpilled) sometimes just cause I like a good debate but I don't discuss the lore of my people with nonwhites and bluepills.
There's only one black guy I like to talk about Norse myth with but he's pretty good for one, he knows about white genocide and but he stands up for his own race too and has a interest in their mythologies.
Other than that though I don't really share the lore with people much because I know that most people are degenerates that would warp the meanings. When I heard the mulatto's at my school sperg out "DOOORRRR :DDXDD" (I was still in HS when the first thor came out) I just walked away and didn't say a thing. I mean if people ask me about my Thor's hammer I'm usually honest but not with some people.
Atheists actually seem to react more against being Pagan than Christians do, Christians will disagree with you but seem to understand that you at least believe in higher power like them, unless they're the weird types that think Halloween should be banned or some nonsense.
Atheists though seem to think that we're all Wiccans but so do Christians
