This answer is assuming that you are working in United States or a Western country, where there is more of a social stigma against discrimination. Like you, I find such behavior repugnant, and I am generally moderate in my political views, not a SJW or ultra liberal or wokegenerally moderate in my political views.
That been said, I don't think direct confrontation via meeting is wise. I am giving the benefit of the doubt that your company executives are not being intentionally discriminatory, but that such views are due to ignorance. Your colleagues who said that more needed to be done are your biggest assets here. Forming a group where certain uncomfortable issues can be discussed openly is a first step. As a minority myself but who was raised in the USA for over 25 years, it's been my experience that while there are individuals and groups with hateful ideology, insensitivity is driven more often by stereotyping, trying to create a scapegoat, or pure ignorance. Your goal is not to directly tell people their views are unacceptable, but assume good intentions through raising awareness.
More generally, if you see another person being harassed / discriminated against , and that individual is unable / need help to defend him or herself, it should be fine to intervene. The idea that only a member of the discriminated class (racial minority, LGBTQ etc.) can respond is problematic as harassing behavior should not be tolerated at work. If the harasser says the victim does not care, you can say that you do and how it makes you uncomfortable. Assisting in creating a comfortable workplace for all should not be seen as savior behavior.
