It'd be more like coming outside and seeing someone wearing the same shirt as you because they bought their shirt from Macy's just like you did. And now you're all like, "What gives you the right to shop at Macy's, you prick?! Guard your grill, fool!"
Yeah why not ...
Now add to that mix that you are xenophobic asshole, raised to believe that you are above all and everyone, and you DO believe that, add that you have litteraly no respect for anyone else, nor you acknowledge litteraly any rights to them, then you add the fact that the very presence of that person is insulting you (just as Kithrak explicitly said), add the fact that that shirt from Macy's (whatever that is) is made specificly by your people and even tho it is potentialy sold to others, you didnt seen even single one on this place you are right now, but you know there are other scouting parties of YOUR people who are wearing EXACTLY THIS uniform ... and finaly add the fact that person is HUGELY outnumbered and outguned and you just killed bunch of them, bcs you simply wanted to, without any consequences.
And then tell me with all this that you would simply wave your arm and just let it be.
