Getting back on topic, does anyone have any idea of the % of real airline pilots on here ?
It's not a very tough question.
There are no easy answers.
I can tell you this: PPRuNe members quick to bash a particular manufacturer (A v B) are very likely not flying for a living. The same applies for the overly sensitive folks who staunchly defend even mere wisps of criticism against their chosen brand of big aluminium tube maker.
As an aside, mechanics aka our ground engineers are completely excepted from the above general guide. Those guys learn their prejudices the hard way via frustration, sweat, headache, heartache, and/or bloody knuckles.
