I think we should also keep in mind that sometime we post for support and sometime we post just for a discussion.

A discussion doesn't mean rude arguements but different point of views on a subjet. It doesn't mean we have to agree, just, state our point of view. Discussion can be interesting and we can learn a lot. Learning should always have a place in our life. We can discuss and respect at same time.

When it comes to support, we should keep in mind that if the poster is asking for the support it means the poster is hurting right now at the instant he/she has posted and the poster doesn't need more hurt. So if we can't say something nice to uplift he/her spirit, we shouldn't say anything. Also if we can't found any words to say to this poster, who is hurting, a simple "icon" can do so much. At least the poster knows he/she has been heard.

Thank you!
