"Some teachers argue that small children are unable to understand what giving their consent means or understand the Pledge they are taking."  

When did the daily saying of the Pledge of Allegiance stop occuring in our schools? Teachers that "argue" this nonsense should not be teachers and should be removed. They must have a huge attitude problem and are unwilling to do the job paid for by American taxpayers. The entire purpose of education at home or in schools is that children, small and big, learn the meaning of words and ideas by repetition: whether please, thank you, I love you, I'm sorry, addition, subtraction, the times tables, etc. Teacher that may this "arguement" may personally disagree with the Pledge or hate the United States and wish to obstruct the student's education of all that the pledge says about the United States, our symbols and their meaning: flag, republic ,one nation under God, liberty and justice for all. If a teacher cannot or will not teach the Pledge of Allegiance, it is likely that they are also not properly teaching American History, World History or citizenship and  key core values.
