Different cultures have different reactions to other humans that are outside of the group. Some take aggressive stances, others practice a more welcoming approach.
The Sentinelese people react violently to outsiders, but many (maybe even most) first contacts of Europeans with various natives was peaceful on the part of the locals.
There's enough variation even in just the modern world that I'd feel comfortable saying that aggressive responses to strangers/outsiders is not inherent but a feature of some cultures.
Why it's in some cultures and not others is probably a very complex topic worth investigation.
You are both in agreement it seems. Individuals could be predisposed to xenophobia and racism but external social structures and cultural forces could overcome those predispositions in some circumstances.

I think it's sort of telling what the evolutionary stance is on being peaceful and welcoming. Look what happened to the natives as a result. In fact being unwelcoming and aggressive can be seen as a show of strength, which is evolutionary advantageous.
