As you pointed out, none of us have to open these threads or comment on what others post. Yet you choose to do that. You can't have it both ways.

I do try to respond to what others may post in a discussion and I may not always agree with their views.

I do try not to post just to moan about what others choose to post or post only to make personal judgements about them.

However, I may not always succeed in every case. And as I have been publicly judged here not to be a nice person - what can you expect?
