start with the definition of a minority.
A minority is a culturally, ethnically, religious or racially distinct group that has a shared sense of collective identity and community that coexists with but is subordinate to a more dominant group with socially shared rules about who belongs and who does not.
This is not a very good definition of minority. There is no sense by which you can get from Ignatius' posts that he is referring to Christians as
ethnoreligious minorities, since there's no mention of the numerous Christian ethnoreligious minorities (e.g., Copts, Assyrians/Syriac people, Chuvash and other Christian Turkic tribes, etc.) that exist in any of the posts, and I know he knows about at least some of them because he's posted about Coptic people before, and Coptic people are the largest single Christian ethnoreligious group in the Middle East.
You appear to be simply trying to shift from the much more common numeric definition of minority (as in "less than half"), which is the much more sensible definition to assume is being used here, on to some other, ethnic definition. I don't really understand why, except maybe that it makes it easier to carry on posting things that are demonstrably false. Like this:
You are talking about a undefined subset of individuals who don't share a common belief or opinion of the general public.
No. I'm asking that you back up your assertion that Christians who hold to traditional Christian anthropology are somehow not in the minority. Can you do that, please?
The common belief may be religious but it isn't a religion itself even if it were a common belief doesn't make them a distinct group.
No one is claiming that the belief is a religion itself (you don't need to be Christian to not buy into the claims of sexual essentialism whereby you are what you repeatedly do), so that's immaterial, but again, if we take the much more common/not needlessly ethnicized definition of "minority", I don't know how you can claim that they're not a distinct group. They're a distinct group, just as those who hold to other anthropologies that are more amenable to the redefinition of humanity inherent in LGBTQIA+ advocacy are likewise a distinct group.
There is no shared identity just a loose collection of different people.
How is there not, if the question is "Are you pro or anti-X?"? Everyone who is pro-X goes in the pro-X group, and everyone who is anti-X goes in the anti-X group, and then bam, you have your answer as to which is a minority and which is a majority, assuming they aren't split 50/50. This is really not that complicated.
There is no community especially in the physical sense. Your group has no neighborhoods in larger communities for example.
There are distinct Christian quarters of Jerusalem, there is Coptic Cairo (and distinct neighborhoods like Shoubra in modern Cairo), there are all the settlements in Lebanon in and around the Qaddisha valley (as well as distinct areas of Beirut, like Achrafieh), there are the Nineveh plains and distinct Christian areas of Baghdad in Iraq, there is historical Beth Nahrain (Iraq/Syria/Turkey/Iran), Tur 'Abdin in Turkey (Mardin), Qamishli and the other Syriac settlements in Syria (in addition to the Armenian villages of Kessab and Yakubiya), New Julfa (Armenian quarter of Isfahan, Iran), the Christian areas of southern India (Kerala) which are home to the majority of Orthodox Indians, as well as the Roman Catholic stronghold of the Indian state of Goa, etc., etc., etc.
These would all be examples where traditional Christians live where they are distinct from the larger non-Christian societies.
I suspect you mean to only be referring to America, which is sort of pointless because the entire point of the American experience is that such divisions aren't necessary to maintain since we are officially a secular country, but that doesn't mean that you can't find places where particular religious or even ethnoreligious groups predominate. The Assyrians (Christian ethnoreligious group from Iraq/Iran/Syria) have certainly claimed certain parts of Chicago, and there are over 50,000 Copts in New Jersey alone.
You don't have a collective identity.
Not
cross-communally, no, but there is still a shared anthropology among traditional Christians by virtue of their being traditional Christians, so I'm not sure how true that is, at least in this narrow sense.
You aren't subordinate to another more dominant group, you may like to play the victim card here but no one is trying to take away your right to marry or to fire you from our job. No one is working to allow business to refuse to sell you their good and service
Again, I believe that the point in saying that traditional Christians are a minority is not to make these kinds of claims to begin with, but to simply point out the likely numerical reality as concerns this issue.
