I definitely don't think Trump will be "Hitler 2.0". He probably won't even be in office after this election.
Again, however, my primary argument is normative and values-based. I'm not arguing that we only have gun rights because they don't kill x number of people. Even if a hundred thousand people were killed by mass shootings I wouldn't support gun restrictions. We don't restrict people's liberties because others break the law. The thing most gun grabbers miss and that most gun rights proponents won't say is that our primary value is liberty not saving more lives.
