There is a lot of partisanship in discussions on this site as you have come to realise. Grow up yourself. If that is not to your liking don't read the thread. There is no question mark to the thread title because of partisanship and to foster livelier debate.
Well, the discussion is really lively, especially when someone whines that others' sarcastic comments lack respect, and asks them to leave this forum. I am curious how these folks grew up.
There is nothing wrong with the title. There are a lot of bold people here (they don't make predictions but declarations) who are made to eat their own words week in week out. (I am not one of the bold ones.)
I am glad you have sufficient insight to know sarcasm when you fling it around and nobody is asking for respect. Targeted sarcasm or an attack will invite a response quite appropriately. I am a little uncertain that about your English comprehension - nobody ask you to leave a forum: simply not to read a specific thread if it distressed you because of its partisanship beginning. This is off topic and I do apologise for that.
