I do not like the turn this takes. SharonA has posted a whole list of Joe's opinions (in order to demonstrate that they are not consistent) in the permathread. If it is a questions of opinions as such you should vote that these opinions have to be deleted as well. Or does Joe only have the right to post there opinions which the posting majority agrees with? The idea to these threads was that one person gets the right to edit these threads and that was a good policy I think.
Joe might of course decide to delete his post in that thread, but he might also say 'if you don't like my way of handling that thread do it yourself'. I wouldn't like that option at all.
