Staff have even said that a Zoner faction, or even all Zoner factions, aren't representative of all Zoners.
Zoner hostility is only true when you announce that you have a vendetta with all of them (e.g Nomads, who are hostile to all Zoners). Saying you're going to shoot a single Zoner, or even a group of them, is like a drop in the ocean.
Saying you have beef with a Zoner base though would only really warrant hostility to that specific base.
