Can't tell from your post if the threads are stripped, if they are then there are good answers above. If they are not stripped I have two thoughts. The seat post may be the wrong size for the seat tube, or you may not be tighting enough. As a suggestion try some " carbon fiber assembly paste" on the post, it will add some friction and may stop the slipping.
"When I hear another express an opinion, which is not mine, I say to myself, He has a right to his opinion, as I to mine; why should I question it. His error does me no injury, and shall I become a Don Quixot to bring all men by force of argument, to one opinion? If a fact be misstated, it is probable he is gratified by a belief of it, and I have no right to deprive him of the gratification."
