I dunno.

If it were determined that red-haired people in Canada had been singled out, for most of the past century, with discriminatory, anti-red-hair-people policies, damaging their lives and robbing them of benefits that everybody else takes for granted...

... I would say that phenomenon would be pretty newsworthy for several years as the unfairness were getting addressed by new policies...

... and yes, yes, that comment (on attention by the press and politicians) would be true EVEN IF red-haired people were only about one percent of all Canadians...
