Never once in my 20+ years working for corporations and government contractors, including companies with very strong DEI programs, have I ever felt excluded or marginalized. And I've never witnessed "reverse racism" (which is a totally absurd name for what would just be racism).
What I have experienced, several times, is people who look like me thinking I'm one of the boys, and flat out telling me they don't hire woman because they "cause too much drama", or only hire women they want to have sex with. And those are just two examples of dozens. Thanksfully those situations have plummeted over the years.
You flat out will not get an equitable work environment if you don't place a focus on it.
