Dhamma Or Ethnic Buddhism by Ven, S. Dhammika :
"Dhamma is universal, it transcends culture and ethnicity. The practice of the Dhamma is not the special preserve of any particular ethnic group.
Let us practice the Buddha’s teaching, not Thai Buddhism, not Tibetan Buddhism, not Burmese Buddhism or any other culturally-specific expression of the Dhamma. Let us practice the Dhamma with a minimum of cultural trappings."Exactly, this is what it should be for all, the so-called 'Buddhists'. Why should there be any differences? Dharma is Dharma but then, there are different versions, and unfortunately, the versions are different based on different traditions or ethnicity....
For example, the issue on vegetarianism, there are different versions of it. Some argued Buddha mentioned it in certain sutra while the other argued Buddha never really mentioned it.
In cases like these, it is up to individual Buddhist to decide based on their own judgement. For me, although there is no concrete evident that Buddha actually set any rules about not eating meat, we should check it against the other teachings that are related to it.
For this issue, I personally believe that Buddha did promote non-meat meals since the 1st Precept of the Lay people vows (the 5 Precepts) is "to abstain from taking lives", so it is logical that we should not be eating meat since in olden days you need to do your own slaughtering if you are preparing meat for your family.
In conclusion, for us to practice Dharma without any strings attach to ethnicity is rather difficult though not impossible. When we are open to all and not fixed to one tradition, the path may be too confusing too...
