Ahhh, my dear friends, I am sure that whoever the person is who has caused discomfort did not do it on purpose or to convert anyone ... I think that "Strangers" and "Newbies" who want, seriously, to join us have the need to establish a personality so we can get to know them.
I have found, in perusing the Posts, that simply not commenting on a Post causes the Poster(s) to re-think the way they are posting.
It has happened to me a couple of times following a post that held no interest to the Board and I have ceased and the thread has changed. I have taken no offense, rather have just plodded along cheerfully.
Some successes, some failures.
That's life on the Board!
