This is a statement that is essentially true, but it’s either irrelevant, or has no essential meaning in itself. For example, “If you want to be in a relationship, you just have to find someone who wants to be with you.” Well, this is technically correct, but what is it saying really. It’s nothing. It’s an empty statement. If person A tries to explain to person B why they are Forever Alone and then this is the reply, it’s saying nothing, but really it’s worse than nothing. It’s using an empty statement to say something, rather than meaningful words that would refute (or affirm) the argument.
Other examples. “You just have to be yourself to attract someone”. WHAT DOES THAT MEAN? Nothing. It’s a vacuous truth.
BS IS BS
