I agree with targeting underrepresented groups. What I don't agree with is statements that are (allegedly) "okay" when one race is filled in, but not okay when another race is filled in. To me, that is the definition of a racist statement... it's pretty clear that filling in "white people" would make this statement unacceptable... so why is it okay to fill in other specific races. There are plenty of ways to characterize a place as welcoming without reducing people to their race.
To echo a previous comment, the absence of one does not make it lesser or undesirable. This is not a zero sum game.
> it's pretty clear that filling in "white people" would make this statement unacceptable
Of course that's unacceptable because it's an implied norm and saying so explicitly is offensive.
If I may suggest? Consider it this way:
"Black and brown people are especially welcome because of their history, life experiences, and unique viewpoints towards something that has historically affected their community's everyday existence ... in addition to the more common applicants (white males)"
NOT:
"Black and Brown people: yay. White people: booooo"
