I think that TCT is a liar, a fraud and a cheat. Freedom of speech allows me to have, and repeat that opinion. Whether I am right or wrong, is not relevant, in terms of how she is perceived by others. That's my opinion, and that makes it right, even if not correct.
You can have any opinion you like, however when you start to broadcast that opinion, freedom of speech does not excempt you from slander, or in this case libel.
Whether you are right or wrong will indeed be relevant, should the other party decide to take action against you.
