we should find as little as possible (outside of torah) to argue about
That is the intended outcome – after you hear what I have to say, you delete all your arguments out of sheer embarrassment as you come to understand the true logical and rationalistic explanation of whatever topic you are talking about. It is a lot of fun.
Especially on an online forum, where you know that what a person writes isn’t necessarily what they think. In fact, one of the posters here told me that he enjoys taking a side in any discussion/argument – whether he agrees with that side or not, depending on his mood – to take the intellectual challenge of arguing your point until the bitter/sweet end.
They aren’t real Machloikes (not including the MO/Zionist etc.), merely exchange of opinions in an intellectual discourse.
