One of my great irritations is being told some X group of people is Y, resulting in Z. X, Y & Z are all monaural in nature, we think. We? This mono is a term that has lost its use in our glitz media age, I suppose because humans have 2 ears, and so should be able to hear stereophonic, not just monaural sound, and because we also happen to have stereopsis vision [2 eyes]. This assumption of consistent stereo sound and sight, is, of course, false, given the incident of humans who, with either or both ears or eyes [or both] are non-functional.
However, politically, too many think our political sensibniities ought to be mono, not stereo. Therefore, as in this case, all Rs are X, all Ds are Y, etc.
That is, by the first paragraph mostly absurd, given the sensibility of most of us is with two functional eyes, and two functional ears. So, why should our political, cultural, linguistic, or even race [if there was one, but the Human Genome Project, in 2003, determined the existence of race is strictly not], by mono?
Absurd notion. Every group, regardless of number [i.e., greater than one person] has as many expressions. Do not throw us all together, monaurally, because we are not. All Rs do no tell all Ds to leave the country if they do not like it.
it's just poor grammar, and not very social, either. Or, what's the term? Tolerant? Now, there's an overused, poorly felt sentiment.
I think SergeantLynch has the wisest comment here: Stop whining; enjoy the dance.
