Adding to what the other guy said, trying to get Republicans to convert to your side through FACTS and LOGIC is a fool's errand. Always has been, always will be. This is why the Democrats keep losing; they focus too much on the enemy and not nearly enough on their own base (which, I should say, already outnumbers the enemy massively; they frankly don't need anybody else).

At the same time using such framing reinforces the very foundations of Fascism in their minds such as the Racism (bombing brown people is fine), Nationalism, Militarism, "Might is right" and so on.

I've lived in a couple of countries, including the UK which also displays a similar mindset to the US, and my conclusion when I saw Brexit up close over there is that the line from the constant cultivation of Nationalism and Delusions of Grandeur amongst the population by pretty much the whole of the Mainstream Media, to Brexit, is pretty direct - people were both Racist against other Europeans and believed Britain would get whatever it wanted from the EU when it left it (hence favored Leave) exactly because during their whole lives they were constantly fed by both politicians and the press a view of Great Britain where the "great" wasn't just a reference to the physical size of their main island.

To me it seems the US suffers from this problem to a larger extent than Britain (for example, Brits aren't made to, in school as kids, constantly repeat the pledge of allegiance), so keeping on reinforcing this, especially in the minds of far right muppets, isn't going to help.

Besides, a lot of the Trump vote seems to have come from people being crushed by the system in the US who were swindled with the far-right siren-song of "blame foreigners", so maybe Democrat figures should be focusing on being "the Party that cares" rather than just carry on playing the strings of Militarism and Nationalism alongside the other guys: being attractive to far-right muppets (i.e. a slightly less Fascist party with some make-believe identitarian bullshit that's still racist as shit - hence perfectly happy with massacring brown people - just with different "worthy identities") isn't exactly delivering a Democrat party that's worth having and what would be real worth it was a party that tries to improve the lives of the many thus attracting voters from amongst the disenfranchised that Trump swindled and is currently busy betraying, and that path doesn't need to blow the far-right dog whistles of Nationalism and Militarism.

This type of "By you're own logic" framing doesn't actually get results. All it does is reinforce a militarist viewpoint as the natural default for Democrats, as well as Republicans.
