you mean xenophobic

the roman empire incorporated barbarians and traded with them, killing off was only meant to safeguard their realm or to get new slaves to keep their society going....

they invited barbarians into their culture and army to use them as troops and to spread the imperium

and the imperium romanum fell because of a need for labour and overstretched lines of communication and supply.

but the emperor fought wars against humans that were technologiccally superior and had knowledge of chaos, take the interex in horus rising, from about pg 330 onwards

"but let me be quick Kaos is a primal force of the cosmos. It resides within the Immaterium...what you call the warp. It is a source of the most malevolent and complete corruption and evil. It is the greatest enemy of mankind both interex and Imperial, I mean because it destroys from within, like a canker. It is insidious. It is not like a hostile alien form to be defeated or expunged. It spreads like a disease. It is at the root of all sorcery and magic. It is...‘It is the reason we have kept you at arm’s length.

[...]

Let me finish, Loken. Kaos, when it manifests, is brutal, rapacious, warlike. It is a force of unquenchable destruction. So the eldar have taught us, and the kinebrach, and so the pure men of the interex have stood to check Kaos wherever it rears its warlike visage.Tell me, captain, how war like do you appear? Vast and bulky, bred for battle, driven to destroy, led by a man you happily title Warmaster?Warmaster? What manner of rank is that?Not Emperor, not commander, not general, but Warmaster. The bluntness of the term reeks of Kaos. We want to embrace you,yearn to embrace you, to join with you, to stand shoulder to shoulder with you, but we fear you, Loken. You resemble theenemy we have been raised from birth to anticipate. The allconquering, unrelenting daemon of Kaos-war. The bloody-handed god of annihilation."

(and the interex were power armor using, starfaring people with access to the warp, highly civilised and technologically superior, peaceful and so on.

or to quote the alpha legion on the emperor of mankind "Legion" pg 131: "He wishes to unify and perfect humanity thro ugh the intense application of martial violence"

also nicxe: bring in hrous rising pg 49

an iterator of the imperial truth on the matter of why  they fought:

ay. ‘The souls we have lately conquered believed in an Imperium, a rule of man,’ Sindermann said as soon as the last flutter had faded. ‘Nevertheless, we killed their Emperor and forced them into submission. We burned their cities and scuppered their warships. Is all we have to say in response to their “why?” a feeble “I am right, so you are wrong”?’ He looked down, as if in thought. ‘Yet we are. We are right. Theyare wrong. This simple, clean faith we must undertake to teach them. We are right. They are wrong. Why? Not because we say so. Because we knowso! We will not say “I am right and youare wrong” because we have bested them in combat. We must proclaim it because we know it is the responsible truth. We can not, should not, will not promulgate that idea for any other rea son than we know, without hesitation, without doubt, without prejudice, that it is the truth, and upon that truth we bestow our faith. They are wrong.Their culture was constructed upon lies. We have brought them the keen edge of truth and enlightened them. On that basis, and that basis alone, go from here and iterate our message."

so basiccally: we  will force our own system of belief on everybody elsde because form our standpoint (we have been taught to think this way) it is the only righteous one and because we have faith in what we do is the correct thing, we can do it. guys, that is one of the motivations that was used to get done with the "endlösung der judenfrage"

if empi was that hell bent on preventing chaos, why not inform his primarchs against it, only ones to actually know, was the alpha legion and  certain parts of the dark angels ( as they had access ot the knights of lupus chaos library (actually only the lion but meh tainted leader of a corrupted legion)

also the north vs south in the us comparison is pretty flawed

they were fighting about power in the union, nationrights vs states rights and the basis of their economies (farming vs "industry")  resulted in fights..

also if that war had brought the south and north together, you would not have had jim crowe laws, segregation or a civil rights movement... that former slaves were not better off after that war than before... revival of the south in the 1870s+ made sure of that.
