First, you made no indication in your very general post about any specific thread here. If you wanted to address that, you should have either replied in that thread or made it clear in this one right at the start.
Second, no one said anything about excluding unbelievers. What I'm saying is that unbelievers cannot expect to come to a Christian support forum and never see a word they don't know. I look at just the post titles of some other forums and have no clue what they're about, important as they may be, but I don't go chastising the people there for not always keeping the vocabulary on a third-grade level.
Third, coming in here and passing judgment on us all because we don't write what you like is not exactly a good witness on your part, now is it? People who have the most to say about other's faults usually have a blind spot of their own. We can't please everyone and shouldn't be expected to.
I did say we'd explain anything asked of us by any unbeliever, and that is reasonable. And I have no intention of getting dragged into another useless debate with someone marching in here with an aire of authority, so this is my last reply to you.
