Why is our site named judaism.stackexchange.com? How come not yahadut.stackexchange.com? Our StackExchange website is about Judaism. But we are Jews, so we should call it Yahadut. For whatever reason (perhaps because they are proud of their heritage), Muslims call their religion Islam and not Mohammedanism, which is not part of the Arabic language. Why has the American Jewish establishment eschewed the Hebrew-language term Yahadut by choosing the term Judaism as the "official name" of our religion, especially when in this day and age we are supposedly always ever so eager to use the Hebrew language (because so many Jews now live in Israel and speak the Hebrew tongue)? IMHO, we should have more pride in our culture than members of other religions have in theirs. Kind of like Kinat Sofrim. The official name of this website is Mi.Yodeya, but why not change the website URL from judaism.etc. into yahadut.etc.?
For more of what seems to make sense to me, please take a look at this comment of mine. (open it in a new tab or just read the quote below)
we don't use English here. We say shabbat and not sabbath, tefillin and not phylacteries. Believe it or not, but these words are not English.
