hi.
Never tell That we are jw or the householder Will tell us to go to hell;)
as a still "active" jw for family sake, when i go to FS (not more than 3 hours per month...) i quickly say That we are jw so That every time the householder Will say he is not interrested...less time lost;)
but personnally i NEVER give my name, because i do not want to be exposed as a jw anywhere later(say...at work or else) while i do not believe those BS. I notice That people do not recognize me later in another context (gas station,bookshop,etc) than the formal door to door.
