As per google's dictionary:
Skeptic: 1) a person inclined to question or doubt all accepted opinions. 2) a person who doubts the truth of Christianity and other religions; an atheist or agnostic
...
Skepticism or scepticism (see spelling differences) is generally any questioning attitude towards unempirical knowledge or opinions/beliefs stated as facts, or doubt regarding claims that are taken for granted elsewhere.
...
Skepticism is the process of applying reason and critical thinking to determine validity. It's the process of finding a supported conclusion, not the justification of a preconceived conclusion.
So I think if someone "doubts the truth of [Buddhism]" and "has questioning attitude towards ... opinions/beliefs stated as facts, or ... claims that are taken for granted" and would like to "apply reason and critical thinking to determine validity" -- and asks questions with this objective in mind then perhaps we should make it explicit.
I see two benefits:
- Makes it easy for the newcomer skeptics to find preexisting sceptical questions.
- Helps the answerers and the audience decide whether they are interested in the question without having to open it. This includes using the favorite tag / ignored tag feature to highlight or gray out certain questions.
I believe this is the intended usage of tags and will make this site easier to use and navigate.
