What does ‘they’ stands for?

What does ‘they’ stands for?

The passage below is from the web site as follows:

https://www.blackstudies.ucsb.edu/news/announcement/509

Audre Lorde is famous for profoundly exclaiming: “For the master’s tools will never dismantle the master’s house. They may allow us to temporarily beat him at his own game, but they will never enable us to bring about genuine change. Racism and homophobia are real conditions of all our lives in this place and time. I urge each one of us here to reach down into that deep place of knowledge inside herself and touch that terror and loathing of any difference that lives here. See whose face it wears. Then the personal as the political can begin to illuminate all our choices.”

First, in this Audre Lorde quote, I want to ask what ‘they’ refers to. It seems to stand for ‘master’s tools’. (Am I right?)

Second, does the ‘difference’ mean the difference as the minority, that is as woman, as black, etc from the majority? (Am I right?)

Third, does ‘knowledge’ mean knowledge of the difference imposed upon her as the subject of racism and homophobia? (Am I right?)

Last but not least, does ‘it’ refer to ‘knowledge’? (Am I right?)

Thanks in advance.
