Rav Kook said that we should also love non-Jews (Middot haRaya, Ahava). Rav Ovadia permitted saying a “mi sheberach” for a ‘םומגקג Druze soldier and a hashkava for the Druze police officer killed in the Har Nof massacre as they do not worship idolsץ Rav Moshe allowed honoring a non-Jew who benefited the Jewish community. Chazal instructed us to give tzedaka to non-Jews, to visit their sick, and to comfort their mourners as the Torah’s ways are ways of peace. This would seem to be in line with the comment seen by the O.P.
Of course, As Rav Tzvi Yehuda (Kook) said, this does not obviate the halachot regarding distancing ourselves. This is a dichotomy of Judaism. On the one hand, we are universalists, and on the other hand, we are particularists.
