That's not discrimination. The problem is when you assume someone isn't the best candidate because of (pick (religion, origin, language, disability, ...)) but you don't know that.
A lot of people have used your way of thinking to justify discrimination. "Obviously foreign people are less educated. I'm just looking for the best candidate so I should not interview someone with a foreign name". How can you be sure that _you_ are not discriminating ?

So you don't agree that your job is to hire the best person without discrimination ? Or you don't agree that giving people the proper tools allow them to be the best version of themselves ?
