What reasons do social conservatives give for wanting to change "Atlantic Slave Trade" to "Atlantic Triangle Trade" in Texas Textbooks?

While doing a little research on the reactions and
statements from Texas Board of Education members who voted yes on the changes, I found
little discussion specifically referring to the change from Atlantic Slave Trade to
Atlantic Triangular Trade.  There were other quotes and actions, however, that perhaps
gives us a window into their thinking.

Another change that
was made was to add the contributions of Confederate politicians to American society to
the lists of people students should analyze.  Texas is, after all, a southern state, and
was also a slave state before and during the Civil War.  On could argue they were
changing the wording regarding slavery to make it more accurate, but I would have to
disagree.  The slave trade outlived the Triangular Trade for a long time.  I see it more
as an attempt by southern social conservatives to whitewash the history and paint the
South in a more favorable historical light.  This is just my opinion, of
course.
