I may or may nor be an XXXj.
I know English, French and Persian.
I like English.
French is okay.
Persian is crap.
If I ever learn another language, it would be either German (cuz I like it) or Spanish (cuz like 20% of the world speaks it?)
Plus, 90% of the world's languages will be extinct in 50 years. No one wants to learn Japanese or Urdu - Fuck that. It's not practical.
Oops, I didn't even read the OP, so I probably did not address whatever question you had.
But sure, I think Ne types would want to learn languages because of their insatiable curiosity.
