During a school board meeting Monday, Navy veteran Michael Copeland said the incident demonstrated "the height of disrespect" to America, The (Columbia, S.C.) State reported.
High school teacher Scott Compton is on paid leave and has until Jan. 24 to appeal the termination recommended by Superintendent Stephen Hefner after the complaints were aired. The final decision rests with the seven-member school board.
Compton, who taught at the high school for seven years, is under fire for removing a flag from the wall and trampling it during three honors English classes in December. His lawyer, Darryl Smalls, has said Compton's action wasn't meant to be disrespectful but was part of a lesson on symbolism, The State said.
No one spoke on Compton's behalf at Monday's meeting.
