Anyway, this is silly:
Statistically, a person is more likely to be hetrosexual rather than homosexuality. Are you implying that because homosexuality is not the most common type of sexuality that people who are gay are abnormal and acting wrongly?
Two points:
1) You're starting from a flawed premise, because human sexuality is not a binary position and actually exists on a sliding scale (going from Heterosexual -> Bisexual -> Homosexual; with most people being somewhere between the three points and there being very few hardline heterosexual or homosexual people, not to mention the phenomena of people who are sexuality-phobes usually turning out to be in denial about their own sexuality--the vast majority of people are actually some degree of bisexual with Hetero/Homosexuals being the outliers).
2) Are you being deliberately obtuse and equating beliefs about human sexuality with racist beliefs?
1) If you are asked what your sexuality is, do you declare yourself to be straight/bi/gay (delete as applicable) or do you declare yourself to be 90% straight with 10% homosexual tendancies? Although it is recognised there are various levels of 'sexuality' on a sliding scale, in the real world most people don't bother try to quantify it to the nearest decimal point on a "How gay are you?" chart. People tend to use one of the three common terms, although bisexuals might add they tend to lean towards a certain gender a little more than the other.
2) I only brought up the example as a slightly more extreme example towards your argument that just because a behaviour was common that it was in some way incorrect or wrong. I never even brought up the issue of racism.
People giving themselves a verbal peptalk is common enough that other people don't immediately assume they are suffering from schizofenia (spelling?) and locked up under the mental health act for doing so. Since the idea of people giving themsleves a verbial peptalk is something that psychologists sometimes advise their patients to do, we'll assume that in their professional expert opinion is that talking to oneself can be an acceptably correct and normal behaviour.
Psychologists are not Psychiatrists (the former tends to be a researcher, with very small pools of direct patient contact for when they're not working on a specific research subject, not to mention usually a whole hell of a lot more expensive to get appointments with), but even granting that you're going to have to provide a bit more evidence since I've always heard and read that it was an intermediate step in therapy prior to moving on to internalizing those actions and making them require far less conscious effort.
Psychologist, psychiatrist, psychopaths or whatever. I believe you knew exactly who I was referring to in my argument and you seem to be spending too much time being pedantic over a typo.
The fact is that people do verbially give themselves a peptalk when facing either a difficult or awkward challenge without anyone thinking they are crazy for a given definition of crazy...
In terms of your extreme example, since I am not american and therefore not fully knowledgable on the finer points of the American Civil War then I cannot answer the question. I am assuming on the basis of the tone of the question that the answer you seek is "yes".
Given the presence of the word "not" in the question I asked, you may want to re-read the post you quoted and think about it a bit. The way I worded the question doesn't exactly allow for a simple "Yes or No" response without a follow-up explanation.
Since you started the question with "Should" then the form typically would suggest a yes or no answer, although
usually the person answering the question adds an explaination as to why they think that in order to get all the marks on offer. Being pedantic, you never actually requested an explaination - and certainly you should have guessed I wasn't going to giving one having indicated in the previous sentence that I didn't have any background knowledge of the subject. And writing from a non-American perspective, any question that contains "Should Americans............... be derided for their stupidity?" in it has the default answer yes. Although to folllow that answer up, that can extend to people from other countries as well.
