The Universities and Colleges I am going to list here are actually Buddhist. I did a little investigating and turns out that Buddhism is Atheistic! The only problem is that there aren’t that many out there in the United States. But other than that let me start listing them and I will put locations and links next to them and so here they are!
Dharma Realm Buddhist University- California - https://www.drbu.edu
Naropa University- Colorado - https://www.naropa.edu
University of The West- California - http://www.uwest.edu
WON Institute of Graduate Studies- Pennsylvania - https://www.woninstitute.edu
Here is a link to a list of more Buddhist Universities and Colleges In other countries.
I myself am closest to the University of The West and do plan on enrolling there and looking forward to it. Anyways I Hope you live close by to one of these and or planning to move or go to another country in order to attend at one of these Schools. With all that said I say sayonara and good luck to you all my fellow atheists!
