Google's start page allows you to customize a homepage. I use it often as it allows me to be at any computer and use a consistent set of tools and links from that page. One of the gadgets I added to my start page a few weeks ago was a gadget by the License Professor of http://www.licenseprofessor.com/ I figured this would be a good way to stay abreast of terms I don't always use and I could learn something new.
One question a few days ago was regarding discrimination. When I starting reading the question I immediately thought this would be a simple question to answer. Well, I got the answer wrong but I disagree with the entire question now that I know what they wanted for the answer.
The question went like this... a seller instructs me to discriminate potential buyers when he's at home. He doesn't want these buyers to view his home when he's there. Something to that effect. The seller';s instructions were pertaining to when he's home and not the race, ethnicity, etc, of the actual buyer. The correct answer was "This is legal in federal and state laws"
Frankly, I don't consider this proper use of the word "discrimination". Like another recent AR blog post that mentioned "blackballing", I consider this a dirty word best avoided in conversation because it's more commonly used in reference to illegal activities.

Isn't funny how a word's meaning can morph? But certainly the word "discriminating" is hardly a bad or dirty word and can be used in polite converstaion. Example: You're home is lovely...you have very discriminating taste!
