how did you learn to write your response?
Typing something on an internet forum is not the only form of "free speech".
Let's take this to testifying in Annapolis. You are encouraged to provide testimony in writing, but you are not required to do so. Were you required to prove your literacy before you were allowed to speak, if you did, during the FSA2013 hearings?
If you show up at a county council or school board meeting, do they ask about your literacy or level of education before you may speak?
