I don't think there is any active anti character activities going on. Characters ought to start with equipment that's appropriate to their culture. I suspect the game doesn't take the skill points into consideration one way or another.
Regardless, the normal outcome from meeting robbers is that you get robbed, in which case they'll take your weapons unless they're of very poor quality, and beat you up if you resist. The normal outcome of such a start is to start without weapons, as they're taken from you (although there is a chance to run away). Killing a band of robbers at the start is almost impossible without significant save scumming (and is never without danger, although some tactics can make it almost safe, given appropriate skill, equipment, and abuse of the rules).
Usually "good" starting equipment is a knife and an axe, since those are required to do just about anything. For endurance hunting you can use whatever weapon you have, including a rock, but to process the kill you need a knife, and to build anything you need an axe (and you can't even get off an island without either a real (not stone) axe to make a raft, or swimming (any you may have to train a fair bit to get sufficiently proficient at swimming to get more than two tile even with zero encumbrance, and the water has to be sufficiently warm, which it is only for a fairly short period).
