Leftists Angry at Trump

Why, Trump must be a racist (i.e. someone who questions Obama) to question Obama. Or he's just stupid. No worries about Trump's belligerent protectionism and nationalism, his economic know-nothingism. Trump wants to see Obama's birth certificate. I've never doubted the prez's citizenship: his patrons would never have made that mistake. But there is some embarrassing reason he does not want to reveal the birth certificate. Libertarian politician Wayne Allyn Root said the same thing about Obama's grades some time ago. Why are they secret, he wanted to know. He must be a racist too. But charges of racism, antisemitism, homophobia, sexism, ableism, lookism, logism, tallism, thinism, etc. are leftist substitutes for an argument, designed to silence rather than refute. Trying to shut people up is unliberal and undemocratic, you liberal Democrats.
