Protesters in hong kong are demanding what ?

They demand an end to the proposed law in Beijing, prohibiting secession, sedition, and other rebellious acts against the government.

Explanation:

The government has planned the establishment of an anti-sedition act, which will ban citizens from rebelling or seceding the country, China. This, according to the protesters, is considered a violation of human rights and a restriction on the Declaration of Independence's famous quote,“When in the Course of human events, it becomes necessary for one people to dissolve the political bands which have connected them with another…a decent respect to the opinions of mankind requires that they should declare the causes which impel them to the separation.” They use the first Amendment of the US to refer to the US as a "land of the free" and they expect China to have the same perspective towards human rights. However, police in Hong Kong decides to use tear gas to force them to disperse, causing more civil unrest.

Personally, I would think that Hong Kong's main but unlikely goal is to become independent from China. Hope this helps  3s3 ^-^
