One advantage of the proposed shun is that the group of prominent infantile attention seekers (in the main, Stevenson, Blackmore, Jeffery, Heapy, Nellwood & Howard) will, perhaps, now behave in a more mature manner befitting a public discussion forum, a forum to which young people may be attracted?
Their collective behaviour in recent months has been shameful and perhaps has been responsible for putting off recruits to model engineering?
Resorting to infantile tirades and also threats of violence is an entirely inappropriate way of expressing disagreement with others' viewpoints.
Indeed, when that public expression of an inner infantility has arisen because of pig-ignorance about the configuration of PC's driving steeper motors, perhaps a straightforward retraction and apology would be more appropriate than the astounding display of temper tantrums that came from Stevenson originally?
