"My response to the Senator would have been something along the lines of:

Then you would have been an idiot. Free speech is not untrammelled, for example with respect to political speech, where there are rules and regulations. Speech is free amongst yourselves, as a group of individuals, but Facebook is more like an online campaign rally than a chat at the pub, Twitter even more so. There are regulations on this type of speech, that currently do not apply to Twitter. Why?
