I suspect Spanner is merely complying with a request from a moderator not to post again..

Whether you agree with what he wrote or not (I don't) and even if he has conducted the subsequent debate stupidly as I personally think he has, he should have the right to express his opinion, right or wrong.
If the mods think the thread has crossed the line, they can lock it as they have in many other cases.
