Traditionalists, like everyone else, want a workplace that is respectful and where they can be comfortable just being themselves.
You have a strong sense of fair play. No doubt you are facing your own challenges in navigating your career - getting interesting development opportunities, recognition, and visibility. In fact, interventions for specific groups can almost feel like reverse discrimination.
Traditionalists generally believe the sole focus should be on getting the best business outcome in the most efficient manner. Celebrating individual differences may seem irrelevant to the workplace and incorporating the views of various people (seemingly just because they look different) really just slows things down.
Traditionalists tend to believe the system is a meritocracy - that it works fairly to recognise the most talented employees who are willing to work hard. As a result, there appears to be no need to change the way work gets done and is rewarded in your company. Diversity and inclusion (D&I) seems to be a distraction from the business at hand or a replacement for meritocracy.
