I'd like to throw something out there....
Is making an assumption (and/or sticking by it despite proof otherwise) about someone based on their skin colour intrinsically worse than making assumptions based on political affiliation, religion, country of origin, taste in beer, health care opinions, fiscal views, etc?
On this forum, I see people who decide every day that someone thinks, feels, or acts a certain way, based on a small snapshot of their opinion, and few are ever apologetic for their mistaken assumptions.
Yes it is, karrie. There is nothing wrong in making assumptions, we make assumptions every day in our life. Indeed, there won’t be any science without assumptions, any theory, any hypothesis makes plenty of assumptions.
Thus, suppose you are interviewing somebody. Based upon first impression, you make plenty of assumptions. Then later if some of them are dispelled, well and good, if not, they stay and influence your decision as to whether you are going to hire him.
So there is nothing wrong in making assumptions regarding political affiliations, taste in beer and so on.
When you make assumptions based upon religion, race, sex, sexual orientation, it can get tricky. Again, there is nothing wrong in making such assumption. But if you act upon them (deny black employment because you think blacks are less intelligent than whites), you will fall foul of the law.
It is not wrong (at least not illegal) to hold racist views, it is wrong (and illegal) to act upon them to the detriment of a particular race.
As one office holder once said in Clinton administration (when talking of racism), “we may not change your attitude, but we certainly are going to change your behavior”.
