Its literal meaning only has currency for those seeking political office and they will scrape the bottom of any barrel of obsequiousness in order to garner votes from the most obscure of minorities, sometimes.
For the rest of us it is just about climbing the greasy pole, or trying to. Anyone with an ounce of ambition is going to have to satisfy the demands of the Equal Opportunites Act. Indeed, just to remain in post - in public service, especially - you need to not say disparaging things out loud about "race, colour or creed". It is more than just being fair to all, one must *be seen to be* fair to all, in dealing with the public.
In truth, most of us are doing the grunt work and are not in HR, hiring or firing people. Now that is the sharp end of being "empowered" to discriminate - as illustrated in the experiment where candidates applied under English-sounding pseudonyms and got called in to interview, whereas the exact same CV, under a "non-English" forename or surname gets a rejection letter.
So, if you're not in charge of anyone and you're working in some remote location where the general public cannot hear you express your opinions, it is only your workmates who could be bothered by them. You can sort out your differences after the odd pint, or five.
