All people (including whites and heterosexual males) can be the targets of negative discrimination. No one wants to see themselves or their kids be intentionally disadvantaged based solely on the colour of their skin or their sexuality. Any attempt to create ANY exception to this rule is disingenuous and does nothing but further damage the very thing you claim to be trying to resolve.
I’ve met a lot of people from different backgrounds and one thing I notice is how much we have in common. I worked with people who make less than a few dollars a day in developing nations and it was interesting how the parent stories are almost the same. Pictures of kids and grandkids. Stories about successful kids. Plans for kids to have education and jobs. The scale varies but the concerns are very similar.
