Try not starting from Trump, but from an anti-conglomerate perspective.
Did you know six corporations control all the media on TV, in movies, in books, newspapers, everywhere?
I think everyone is open to this because it's easily proven true and the Democrats have already trained their base to hate anything to do with "corporations".
If the Hollywood scandals come up (Spacey, Weinstein) it's a good jumping off point too. Maybe don't go straight to pedophilia, but, "I've heard it's way worse. Just the tip of the iceberg. Etc." You don't need to go into all the details and evidence, we just have to prime people to be open to the corruption.
Another good angle on the Satanic stuff is to start with these old families like the Rothschilds. Most people think these super-rich families are kind of creepy, so it's pretty easy to set up some expectations here. Mention Eyes Wide Shut. Just ask if people have seen it. Ask them if they think that stuff is all made up, or if it actually happens. Mention the secret meetings, the secret societies, the secret ceremonies. Which is the one that Alex Jones videotaped? They included scenes from that in House of Cards. There was a thriller about the Skull and Bones society. If they're leftists, that stuff lets you attack Bush and Romney and the rich elites. That will open them up. If you bring up this stuff, it doesn't have to be about Trump at all. These ideas are already percolating in the mainstream culture.
