Dear Supporter   We should like to invite you to participate in the Club's consultation exercise on the use of the Y-word.   You may recall that we previously undertook this with our fans in October 2013 and we feel that it is important at this time to again assess fan sentiment on this subject and to examine the appropriateness and suitability of its use.     It is well documented that the Y-word was historically adopted by Spurs fans as a defence mechanism in order to 'own' the term and thereby deflect anti-Semitic abuse at that time in the 1970s.  Its use has continued to the present day, leading to supporters acquiring the nickname ‘Yids’ - albeit the Club is multi-denominational in its composition.   We have always stated that our fans (both Jewish and gentile) have never used the Y-word with any intent to cause offence.   The use of the Y-word has several key considerations – firstly whether or not its use now plays a role in deflecting or, indeed, attracting unjustifiable abuse; whether or not it contributes to a lack of clarity on what constitutes anti-Semitic behaviour by fans; and whether, even if unintentional, the offence it causes to some means it is no longer acceptable to use.   We recognise that there is a broad spectrum of debate across both Jewish and non-Jewish communities on what is a finely nuanced subject.   We would appreciate you taking the time to respond to this consultation and give it your full consideration.     Thank you for your support and taking the time to participate.   It should take you no more than 10 minutes to complete.   Please note that once you click on the link below you will be required to complete the consultation in one session, and you will not be able to return to the page once it has been activated.   All of your answers will be treated anonymously and confidentially. If you are interested in participating in further research associated with this subject, please provide your details in the relevant section located towards the end.   You have until Sunday 18 August to complete the consultation.   We look forward to receiving your feedback.    Best regards      Tottenham Hotspur
