You would be wrong, go to the conservative subreddits and ask them if they believe in it.

Here's a April pew research poll I found after a couple of seconds of googling link

"in December 2016, 57% of Democrats and Democratic leaners, compared with 20% of Republicans and Republican leaners said that blacks faced a lot of discrimination – a 37-percentage-point gap. That has increased to 50 percentage points in the current survey: 69% of Democrats now say blacks face a lot of discrimination, compared with 19% of Republicans."

"In contrast, Republicans are about twice as likely as Democrats to say that evangelical Christians (70% vs. 32%), whites (58% vs. 25%) and men (48% vs. 27%) are subject to at least some discrimination."
