An even more disturbing parallel: Trump wants people of a specific religion databased so they can all be watched by the feds. Know who else databased people of a specific religion so the government could watch them? Hitler. Yellow stars of David on peoples' clothing to mark them as Jews. Trump is no different from Hitler. Same hate, same purpose, different language.
I have been thinking of marketing black armbands decorated with yellow stars of david, or yellow crescents, or pink triangles.
Can't think of a good one for blacks save something based on the black star line's logo.
But it wouldn't fit the theme.
