Not really because it is the same as christianity? First of, what does this similarity have to do with my point?
Your point was that your belief that there's an ambiguity in the meaning of what "Jewish" is meant that it's a meaningless word and a pointless thread. My point is that, if Jewish is meaningless [it isn't] then for similar reasons "Christian" would be too.
Secondly, there is no real similarity. If someone talks about christianity we know they are talking about a religion.
Not when it comes to someone saying they are Christian, nor especially when you look at their beliefs and their actions [and indeed the beliefs and actions of people who say they aren't Christians]
Some people believe they are Christian because they live in a particular country that they consider Christian. You could say that "Christian" means you've been baptised as one - which covers a lot of non-believers. You could say it's following a religion, but there are many believers who don't actively go to church etc. There are plenty who get married, get their kids christened and get buried in a Christian manner who aren't Christians from the pov of their behaviour or stated beliefs. There are gay people who claim to be Christian and Christians who don't accept premises in the bible about women and gays and ones that do. There are Christians who don't believe the bible literally and ones that do.
In short, someone saying they are Christian doesn't tell you much unless they expand.
I don't see much difference w.r.t someone saying they are Jewish, albeit I expect the person who says it has a clear meaning. Equally there are thousands of other labels and words that people apply to themselves and others that I could have used as an example other than "Christian" that, from your pov, must be meaningless.
This bit of the world isn't black and white either.
Mebbe someone could start a thread on Zebras?
