Names are a matter for negotiation between equals. People who know me well know how to address me because they know how I respond to different names. My grandchildren all call me "Gran" because that is the name I chose for myself - unless they want to tease me when they have been known to call me "Granny"! People who know me also know what to call me, because they know my name. People who do not know me only need to show me equal respect.
"Dear", "love" and so on cannot but be patronising for the simple reason that they are not meant. Only people who know me can love me or hold me dear (even if not all of them do).
Of course it is not only the post-60s that are patronised.
