Humans have a inate instinct to fit in, so every time we go against the collective opinion we put our selves in the fireing line. Thick skins are need to protect our egos, so we either become very domineering & singleminded refusing to see another point of view, or we don’t put our heads above the parapet. Being on an relatively anonymous site such as this allows all us to give our opinion within a relatively safe environment,without exposing our true identities or backgrounds.Therfore protecting our egos,ethos & circumstances from further judgements & assumptions.
