The BBC striving for diversity in hiring != Th BBC pushing a “social justice agenda” in its content.

If you can’t see the distinction, I doubt you will find any journalism stooping to your level.

Actually it's more than just hiring practices and directly covers content.

One example would that the BBC now has to have a 50-50 gender split for experts brought onto its flagship Radio 4 Today programme. That was decided to presumably to broaden opinions given to be more inclusive.

Another example would be this speach by Ms White where she clearly states:

"So today we have announced that the BBC will have to agree with Ofcom a new Diversity Code of Practice. This will set out how the BBC will commission programmes that authentically portray the whole UK population." [1]

As to "stooping to my level", I've so far not said anything about whether this process is good or bad or if the ends justify the means. Just that it is going on and you can read about the details if you wish.

You haven't at all backed up the assertion that the BBC are "under _specific_ instructions...to drop impartiality and implement a social justice agenda" (emphasis mine). You provided evidence that the regulator has demanded that they hire and air a more representative mix of gender, ethnic background etc.

Nowhere above has OFCOM directed the BBC to air different opinions. Regarding the Today programme example: Deliberately featuring a female (rather than male) climate science expert after featuring a male vaccination expert is entirely orthogonal to impartiality.

[EDIT:] I'm not specifically arguing that the BBC has no bias. I'm saying you haven't demonstrated that OFCOM have demanded a bias.
