No, the trespasser commenter's personal preconceived notions and views about what humanity is and the responsibilities of a society to its out-group de jour are enable their vitriol. They've been lead to believe "outgroup bad, America good" by what tends to be a right-wing media following. You're not going to successfully fight nativism/tribalism this way. I'm not sure why you keep stapling unrelated issues together, it's possible to have more than one problem at a time.
