Is “Heathen” the religion of non belief and anything goes?
No. “Heathen” refers to a person, and there is no religion of “Heathenism” or similar. By definition, a heathen is a person who does not worship the god of the Bible. Therefore, anyone not of an Abrahamic religion is a “heathen”. This hardly equates to absence of belief, or ethics. In fact, if you compare the histories, there’s no contest when it comes to bloodshed and carnage (hint: the comparison isn’t favorable to the Abrahamic religions). Thus, I think you would be well-advised to not cast aspersions as you do. I strongly suggest you get yourself a dictionary, or avail yourself of one of the free online ones.
