Again, you're not under any obligation whatsoever to participate in any of these types of threads, so isn't any "irritation" self-inflicted?
I mean, c'mon...THE WORLD IS FULL OF PEOPLE WHO DISAGREE WITH US on a host of different topics...should we go around being "irritated" with them, too? Last I read, "temperance" or "self control" was a fruit of the Spirit...as is "longsuffering" or "patience". As such, perhaps such "irritations" ought to get us to take a good, long look AT OURSELVES instead of seeking to place the blame for the same ON OTHERS.
Anyhow, like it or not, there are those Christians who don't celebrate "Christ Mass" and they don't celebrate "as unto the Lord" and there are also those who do celebrate "Christ Mass" and they do celebrate "as unto the Lord". Neither group is going to necessarily make the other group go away or convert, but, again, we ought to be able to CIVILLY explain and discuss the reasons behind our respective choices. For those who are "irritated" by the same, well, again, nobody is forcing any of you to even look at any of these threads, let alone to participate in the same. IOW, just take responsibility for your own actions and your own choices and stop pointing the finger at others.
