It is always interesting to me the discussion of morals in ethics. like who decides what is moral or ethical besides everything coming from a place of love. Other than than morals and ethics are pretty debatable, like i find putting immigrant children in cages reprehensible and anyone who supports it can't have much of a moral or ethical core to me but others feel differently.
If it makes the 4some happy and they are all coming from a place of self-less love, enjoy.
