Given that hiring/firing people is a key part of being a CEO, a racist CEO would result in hiring/firing/not promoting talented, capable people based on irrelevant factors. Speaking purely from a business perspective, this will give the company a disadvantage and negatively impact performance. "Ideology" is too broad of a term the way you are using it: after all, believing that COBOL the ultimate programming language for all use cases could also be labeled an "ideology", one that would make somebody a poor CTO. Similarly, beliefs that certain groups of people, based on unrelated criterion like gender identity, are inherently inferior to others or deserve lesser treatment, do materially impact the workplace. Unlike the previous two examples, somebody's personal beliefs about things like religion or their cultural background have nothing to do with job performance.
