What *they* want you to think is that federation with them is an acceptable idea, because the marketplace of ideas will defeat them in the end.
But it won't.
Nazis don't operate on an intellectual level. They operate on an emotional level where they tell any lie to try to provoke an irrational response.
They try to get people to think their families are in danger if the "outsiders" aren't stopped (i.e. PoC, muslims, LGBTs etc).
Debating Nazis doesn't work.
