It turns out that the atheist group which paid several thousand dollars to put up this billboard is ignominiously taking it down. A thorough search was unable to corroborate that Thomas Jefferson said anything close to what the billboard claims he said:
So, not only is there no evidence Jefferson ever said such a thing, but Mr.Gleason is incorrect in asserting that it nevertheless expresses his true feelings. Not only is there much evidence to the contrary, but only a complete historical illiterate could say that there's not one redeeming feature of Christianity. I think it safe to say that Jefferson would have been offended that such ignorance was imputed to him.
The atheist group that sponsored the sign is not only historically benighted they're also pusillanimous. Here's a test: Unless one is willing to put up a similar billboard saying the same about Islam they really shouldn't put up a sign derogating Christianity. It takes no courage to criticize people you know will do nothing more serious to you than pray for you. It does take courage, however, to broadcast the same message about a religion whose devotees will do all they can to cut off your head for saying it.
Moreover, is this the best that the Cosa Mesa atheists can do with $4000? How many meals would that money have provided in a soup kitchen? How many elderly could have their utility bills paid with that amount? How many vaccines could be purchased for destitute Africans? What good comes from spending the money on an effort to dispirit and discredit the very people who are actually doing these things?
