My objections were not as much to the use of the word 'chosen' - as to the FACT that it is being used by too many in a way which is grossly inaccurate, and so presents a most distorted picture of Jewihs theology.
It's like 'caritas' has a pretty specific meaning in RC theology: so does the concept of 'chosen' in Judaism (ALL Judaism, yes).
And that concept ('chosen' in Judaism) has NOTHING of 'superiority' about it: it is about the J ews being chose by YHVH to live by the Sinai Covenant. As other groups were similarly chosen by YHVH for other Covenants, given other tasks, different work to do in this world. Torah doesn't talk about all of that because we Jews didn't need to know about every little thing YHVH was doing with different tribes of Man. But the overall idea is IN there, several times over: YHVH is LORD over All the Earth - He just chose the Jews to make that fact known to others. As a certain poet once noted:
How odd
of GOD
To choose
the Jews!
We don't know why He chose us to preserve and make Torah available to others: it doesn't matter, because it's about Him - and not about us! His choice doesn't make us any better than anyone else. YHVH is a loving parent Who wants to have a relationship with EACH tribe of Man, as we are EACH His beloved children.
