Seeking clarity of language

As has already been noted in discussion here, in the English language, there is a frustrating ambiguity to the term "Jewish". This ambiguity has been exploited by dishonest people to deny the existence of Jewish in-group preference, which habit produces further anger among those disadvantaged by this in-group preference.

Now, I am not the master of the English language, so I cannot enforce any kind of decision, but we could decide among ourselves a set of terms we'll agree on to discuss this topic and to have maximum possible clarity of the issue.

As I see it, there are three relevant questions as to Jewishness:

• First, there is the religion of Judaism.
• Second, there is the Jewish culture.
• Third, there is the biological race of Jews. (As I understand it, it might be more accurate to say races, as there are several distinct sub-groups.)

Now, depending what person you're talking about, any or all of the three may apply. As far as I can tell, if someone practices the religion, they will also be inculcated in the culture. However, there is a distinct culture which is still shared among those who are not religious. Frankly, as far as I can tell, these days, the cultural, but-not-religious Jew is the one causing the most trouble. I am happy to take correction on that point, however.

From what I understand (again, this is without detailed study, happy to learn better), Ashkenazi Jews, which is whom we in the West largely deal with, are, in fact, a sub-set of Europeans. They have roughly European intelligence (nope, no 115 average). Thus, the biological aspect is of the least interest to me, personally.

So any given person could be a religious, cultural, and biological Jew, a cultural and biological Jew, a religious and cultural Jew, or a biological Jew with no connection to the religion or culture. I suspect the religion does not exist without the cultural factors.

Does this sound like an accurate assessment of the relevant questions? If so, what terms should we use to distinguish these? (Reminder: No racial slurs, please. That is one of the ground rules.)
