That being said, Having said that and That said are all used before saying or writing something contrary to what you have just said/written (meaning "however"). I have also seen "That having being said." Maybe there are more variations for this. My question; Can I just use them interchangeably? No preferences between formal and informal, spoken and written, AE and BE etc.? Thank you. (To the moderators) I've found a thread which is asking and answering the meaning of "that being said". I thought asking about the differences of these similar expressions would deserve another thread.That being said , if I should add this question to that thread, or another thread on this topic exists please kindly let me know.
