Whether or not domestication in the first place was ethical can be argued, but in my view somewhat irrelevant now - in the world we live in now there are millions of cats, dogs, and others who are in need of a home and adopting/rescuing is a morally good thing to do. I would even go further and say those of us with the means have a moral obligation to do so.

Posts like yours do absolutely nothing to help.
