If you were so audacious as to go to the Lumberton Independent School District (ISD) website, you would find the ISD has posted a response, noting the picture of the students in Islamic attire. So it apparently is true that some students in that World Geography class did, indeed, wear Islamic garb. I don't know whether the ISD's description of the lesson plan content, best summarized as "The lesson encompassed diversity education so students receive a firm understanding of our world and why people are motivated differently." is more accurate than someone describing what their High School student informed as the content of the instruction.
In sum, it is unreasonable for anyone, even a troll, to believe the column is 95% false.
