Well we do sometimes struggle with finding the right words. Negro, black, coloured, Afro-Caribbean, black African, African-American, person of colour... Gay, queer, homosexual, lesbian, queen...Asian, British Asian... Same thing with gender matters that we have to tussle with. The thing is, the people like you and me who have to tussle with finding the words are not the people in those minorities who oft find themselves discriminated against, often with the words of language we are now tussling with being the main weapon. To my way of thinking, it's worth our efforts to be respectful enough to find the right words, the words those minorities would want us to use (not necessarily the words they might use among their own). It's hard work, but not as hard as the work those minorities have to do to fight those prejudices...
