Iam not religious at all but having studied the mainstream religions and a few minority ones too. I think Buddhism is the close d think I've seen that makes good sense. So to have a girlfriend who was one would be quite cool I think.
It would be awesome to date a Buddhist. My best friend in high school was a Christian who converted to Buddhism. There are certainly sects of Buddhism I have more of a problem with than others. But in its foundations, Buddhism was very far ahead of its time, with a lot of the concepts being just now verified in fields like psychology and neurology.
So I guess my answer is yes, I would date a practicing Buddhist.
No due to religious differences, although I find women from buddhist countries (China, Thailand, and Vietnam) very attractive.
Only if they are not the praying and fake vegan type. Imitation dog meat curry, fake BBQ pork... etc. I like those imitation food but I don't like the idea people eat those for religious reasons. It makes the whole thing looks fake.
