Whilst some of the points raised by SP may not be agreeable to most and often repeated ad nauseum with little relevance to the subject matter at hand, i do not sit comfortably with banning of someone for expressing a view in a country that allows free speech.
I think that there is a need for reasonable behaviour within postings ie no swearing, abuse of any kind etc but banning someone for this is not the answer. We can scroll past any comments if we choose not to read them as there is no limit on the amount of postings in a subject or subjects.
I would not agree with a ban.
