Alright, so, the fact here is that I don't think you really appreciate how different this setting is compared to the other ones. One is walking into the country of people who nominally dislike the folks from across the border, and the other is walking into the military training range where the most insane of them have decided to take up hunting those folks from across their border and are holding rifle qualification drills.
I cannot emphasize enough how different these stakes are.
You will be a stranger in a strange land.
I'll just leave you with the idea that any kind of assumption that you are in any kind of practiced element here should be tossed out the window.
Thanks for the advice. I do not know if they will be:
Instantly hostile and aggressive without allowing me an inch.
Hostile and aggressive but also capable of being calmed through my own behavior (I have had this experience and they allowed me entrance into their church).
Hostile but also curious (also experienced).
Concerned but welcoming.
Very friendly.
Friendly but partly with other motives, such as them being spiritually obligated to evangelize to me and they think being really nice to me will help win me over to their religious beliefs.
Other.
I have experiences across a range of reactions. If I stopped myself from venturing into new territory just because there was a chance it was new territory, I never would have ventured into new territory at all. That is not a helpful approach in itself. If you are suggesting it is physically dangerous to be there, that would be more of a legit concern. Them having a very different ideology is insufficient reason to avoid them. I will take some cautionary measures like I have before and see how they respond.
