Two participants so far and you two have pretty well covered all the bases
I am occasionally coming by this site, but I primarily still go to Blurtit.com first and then here---partially because I'm not totally used to the format here.
As DaydreambelieverTrumpDisbeliever said, "To educate others"----which I might tweak only slightly to suggest that we can provide other arguments or outlooks that the average busy person may not have had time to get exposure to.
The ad hominems that arise from those who attack (you) "daring to ask a question" are simply the chafe that usually comes along with the wheat.
Anyway, soldier on---definitely.
