Just like the pandemic, conservatism is a global plague. Why are you only taking American conservatives into account? Conservatives abroad are also anti-science, anti-education and anti-intellectual. These are conservative traits, not limited to just American conservatives.
And how am I discounting black people? Conservative =/= Republican. Many black Americans vote Democrat simply because Republicans are infamously racist against black people.
Many of the black Democrat voters are very conservative. Other than the racism, they share the traits of homophobia, xenophobia, misogyny and delusions of religious superiority.
