> I can see that if your mother tongue doesn't use subject-verb-object word order (e.g. if it's German), it might be confusing.

I'm sure you thought this was a witty repartee, but it's just dumb.

Hatred, violence and cruelty by an outgroup against your ancestors, or your ingroup, or your ingroup's ancestors, never justifies you own hatred, violence or cruelty towards that outgroup.

The Nazis believed that the Jews had sincerely harmed them. That of course did not justify them. What made them "the Nazis" is not that they adopted that name for themselves. We know that "the Nazis" were the Nazis because they gassed the Jews, and because of everything else in their rhetoric and policies leading up to that point. In "a situation where the Jews gas the Nazis", the Jews would be the ones in the wrong.

Rhetoric like this is completely uncalled for.
