As described in this article, the term "microaggression" refers to specific interactions between people of different races, cultures, or genders that, while not physically violent, are nonetheless aggressive and demeaning.  They can present themselves in the form of both verbal and nonverbal exchanges, and are frequently not recognized as offensive in casual conversation.  Despite the apparent innocence or good intentions of some of these questions/comments, it is important to recognize the implications of what you say to people and the effects your words can have (even if unintended).   

What are your opinions of these young people's experiences?  Have you ever heard things similar to these?  If so, how did you react?  Have you found yourself saying/asking these things, and perhaps seeing unforeseen consequences?  Do you think these kinds of microaggressions are typical at UMBC?  What do you think is the right way to handle them? 

Please feel absolutely free to share your experiences in the comments, but remember to keep it respectful :-)  Keep in mind that instances in which you identify ignorance should be teaching moments rather than opportunities to put someone down!
