I agree. It´s personal choice and as a reader of posts it doesn´t matter to me whether there´s a comment by the poster or not. As I´ve said before, Ros is not the only member that has this style. Some members merely add the comment that they found the article "interesting" and this too does not give anything away about their personal view of the issue/s raised in the article. They may also ask members what they think of the article. Other members will give their opinion alongside the articles they share.
For me, the interest is in the articles themselves and the level of interest from other members will obviously vary. Reading them helps people to nurture their own ideas about issues in the world, but that doesn´t mean they have to share them in public. I think it´s about personal growth, not debate, for many members here. Of course some articles are simply vignettes of information, which don´t always require a supporting comment, because it´s posted as entertainment in itself. The other extreme is the firwork display mentality, "light the blue touch paper and stand well back". Mostly, everyone is somewhere in the middle. However, whilst I obviously don´t agree with everything everyone posts and sometimes it´s annoying, I do recognise they have a right to post in their own style . . . it´s diversity and who could possible be against diversity of style?
It seems to me, it´s the comments (or lack of in this case) that cause the arguments most of the time. And, for the record, I don´t exclude myself from that (just in case someone decides to comment on my "hypocrisy" or the blackness of my "pot").
If posters want to risk speculation about their views on the articles they post, that´s their choice.
Just as everyone has the right to their opinion, they also have their "right to remain silent".
