:::::Actually I never made a claim that 'no woman could have helped develop Viking', or said 'saying otherwise is historically incorrect'. That is just something that you have assumed by your personal inability to read what was actually written. I am fully aware that some of the best engineers, designers and technicians are female. I personally know and socialise with some highly competent female Phd's, whom I greatly admire and respect. What I did say is that it is wrong to change the wording of a cited source used as a reference to support a written statement, as that is nothing more than wrongly quoting what a person has said or written. Fortunately your comments about me are also incorrect. What that comment does prove however is that you are uncivil and prone to making false accusations about people you do not personally know and making  personal attacks and violating Wikiquette is nit acceptable from any editor. Then again perhaps you enjoy attempting to bait people by being rude, possibly to make yourself seem important, if so then you may find that at some point in the future your editing access gets rescinded.
