Doesn’t work because of the ratios of the populations. For a majority group, their interaction with the minority group is 1 in 100 interactions. For the minority group, they are interacting with the majority group 99 of 100 times.
Being mindful 1 time every 100 is not a big deal. Hearing something hurtful 99% of your day every day is a very big deal and could easily be the most difficult thing in your life.
You can disagree with the reason the minority group is feeling hurt, you can’t proclaim that they aren’t feeling hurt.
And with that being the situation you can only decide whether you have the empathy and belief in common humanity to do your small part in reducing the amount of hurt in the world. Or not.
