英文-句子結構和意思問題

The use of "does it believe that" is called "reversed sentence structure" in English grammar. In a normal sentence structure, the "subject" is placed before the "verb", but the order is reversed in a "reversed sentence structure" under the following situations:
(1) Where are the apples ?
(2) There are apples in the refrigerator.
(3) In the refrigerator are the apples.

When making two negative statements, it is quite popular to use "neither" or "nor" with a "reversed sentence structure".

Example (1)
Tom: I don't like apples.
Kelly: Neither do I
Mary: Nor do I.

*note that the "reversed structure" is also seen in positive statements.
e.g.
Tom: I like apples.
Mary: So do I.

**also note that "neither" and "nor" do not have to work in pairs.

Example (2):
Separate sentences:
I don't like the idea of a divorce.
I also don't like to see a wife enduring an abusive husband for life.
Joint sentence:
I don't like the idea of a divorce, nor do I like to see a wife enduring an abusive husband for life.

Example (3):
Separate sentences:
I don't like to eat beef.
I don't like to eat pork.
I also don't like to eat chicken.
I am a vegetarian.
Joint sentence:
I don't like to eat beef, nor pork, nor do I like to eat chicken. I am a vegetarian.

Therefore, the subject sentence originally contains three negative statements:
(1) It has never tried to sell any political line.
(2) It has never tried to lavish attention on the changing political scene in HK.
(3)It also does not believe that the proper role of a museum is to take part in current political debates.
Similar to example 3, the separate sentences can be joined together, using "nor" for the second negative statement, and "nor" with a reversed sentence structure for the third negative statement:
"It has never tried to sell any political line, nor to lavish attention on the changing political scene in HK, nor does it believe tha the proper role of a museum is to take part in current political debates.

I think "it" represents the "museum", or the "governing body for the museum".

如以文法原則來看，這句有點不妥的，因為三子句如果用同一文法模式，應該是：It has neither (never 配nor其其並不太傳統的寫法，但尚可理解) tried to (verb 1: sell)..., nor to (verb 2: lavish)..., nor to (verb 3: believe)...

如果你能引述這段內容的出處，可能給你多點意見。但就這complex sentence而言，三句子句的組合內容文法與及每句子本身的用詞(例如：sell political line, lavish attention, proper shere(share?) of a museum...political dabate(debate?))都不是道地的英文詞彙。

就對回答意思大約是：它其實也不相信博物館的應有權益是參與當下的政治辯論。囧
