Is everyone entitled to an opinion?

Yes!  But there is one condition, that it’s your field of expertise.  The plumber will opine on the latest pipes.  The doctor will offer his choice of treatment for nose bleeds, and the cheder rebbi will tell you what kind of discipline works best.  

Ok, I get it; you’re all saying, well what right do you have to give your opinion.  I can honestly say I don’t think I give my opinion on issues outside of my league.  I do try to get my writings proofed by those that can give me their unbiased opinions, and more is erased then printed (thank G-d!). 

There's a story of a famous rabbi that was puzzled as to why his children were not following in his ways, while his neighbor the simpleton, merited that many of his children grew up to be great scholars. 

He went to a Tzadik for advice.  The Tzadik explained  to him: "Since you’re a rabbi of great prestige, you therefore feel entitled to give opinions regarding your peers – all the others great sages (and his comments about them were not always that complimentary – to put it mildly).  Your neighbor on the other hand realizes that it's not his place to talk ill about others that are not on his level.  His children therefore only heard great things about rabbis.  Hence they strongly aspired to become big in Torah themselves".

Possibly the simple neighbor was not all that simple.  His approach comes from a place that many don’t reach.  Sometimes the simple path is the truer path.
