it is MUCH more into gender translation than the Nasb/Nkjv , or even the HCSB versions, correct?
I have never heard of the term "gender translation" before. Do you mean that the NIV uses more inclusive language than the aforementioned ones? Yes. Also,the NIV uses slightly more than the NET Bible,and less than the NLT and TNIV.
The ESV and HCSB use much more inclusive language than the 84 NIV.
If the footnotes of the ESV related to inclusive language was put in the actual text then the ESV would rank just a mite less than the NIV in the use of inclusive language.
