I think the primary #1 issue we should focus on over the next 4 or so years is IMMIGRATION.
Specifically, this:
* ENDING immigration once and for all. NO MORE foreigners coming into our country.
* REVERSING immigration, especially illegal immigration. Send them home! Send home all the H1B and green cards as well!
* NO BENEFITS FOR IMMIGRANTS. If we have benefits at all, only native-born citizens get them. Everyone else needs to go home to their people.
* DE-NATURALIZATION for recently naturalized "citizens". Raise the bar very, very high for who gets citizenship, and disqualify those who were given it but do not deserve it.
In the US, our goal should be constitutional amendments that specifically implement these policies. We cannot leave it to mere law, but we must start there. Importantly, we need people at all levels of government who understand this issue and side with us on it.
The MORAL CASE for ending immigration is simply this:
* If you want to help poor people, GO TO THEIR OWN HOME COUNTRIES AND HELP THEM THERE. There are WAY too many of them and too few of us, AND WE CANNOT HELP THEM HERE! Our society is too complex and too foreign to them. Our people are too vulnerable!
* The people who DO come here all too often are coming to sponge off of our hard work and success, or worse. PREY upon our people. We MUST eliminate all the sponges and predators from the immigrant population.
* We cannot build fences around all of our homes and businesses to protect them from immigrants who don't respect our laws and culture. We CAN build a fence to keep people out of our country, and secure our shores as well.
* We are being made foreigners in our own land. The land that our ancestors fought and bled and died for. The land that we spent our lifetime, even MANY lifetimes, building up and civilizing. We are waking up to realize that we aren't wanted here anymore, we aren't welcome, and we aren't comfortable. Our children are going to have to leave our own homes because it is no longer safe for them to be here. We brought the 3rd world here, and now we have no place to return to!
Rhetorically, I'd pull back on getting rid of people already here (except for illegals and temporary students/workers) and focus on stopping uncontrolled migration while raising the requirements for even applying for a VISA (fluent English should be mandatory). The people living here can be made so uncomfortable that they leave on their own.
This goes hand in hand with de-villifying our own culture so emphasis should be placed on how much people want to come here because that implies value that we should safeguard, especially getting "legal" immigrants on board; what happens to the prosperity that they got to access once a billion fighting age males from their old countries (that they fled) show up looking to be paid without working for it?
The Western economic boom of the 20th century was built on the Protestant work ethic combined with the freedom to organize and innovate without onerous government red tape. Cultures of toil (ie doing what you're told, even if you know it's unproductive) and government hiring programs for specific groups (ie immigrants) undermine what has worked for us up to now, as does using infinite foreign labour to undercut local wages.
Basically, take that Smithsonian infographic on Whiteness and present it as a goal to strive for.
We've got to get rid of the recent immigrants, particularly the illegal ones. If we don't, we're lost.
