“Does trump, and by default his supporters and the GOP, tolerate white supremacists/Nazis ?”
Obviously, but the folks here who support him have other agendas than the safety of America and the Jewish people. Trump described the Charlottesville Nazis as “very fine people” and the armed thugs with confederate flags and swastikas who took over the Michigan State House as “very good people”. Trump doesn’t just tolerate them, he supports them. He supported the notorious Steve King, who finally lost a primary last night. And he supported Paul Nehlen, an actual Nazi, in a congressional primary against Paul Ryan.
