Hong Kong has significant cultural differences from mainland China due to its evasion of communist ideologies during the colonial age. After it was handed back to China in 1997, the city has kept their independent and reputable legal system, effective anti-corruption measures, free press that cover a sensitive topic such as Tiananmen Square Massacre in 1989. They speak a different language (Cantonese vs. Mandarin) and write with different Chinese characters (traditional vs. simplified). You will quickly annoy locals if you suggest that Hong Kongers are subjected to propaganda in the same way as people who live in Mainland China.

In general, during a conversation, it is best to avoid subjects of politics. If you are asked your opinion, best to be neutral about it. However, there is no need to worry of getting into trouble solely by discussing politics. In Hong Kong, freedom of speech and the press are protected in law. Hong Kong people are free to criticize their government.

Many foreigners are not certain whether to address Hong Kong people "Chinese", or if it would cause offense. The Sino-Hong Kong relationship, as always, is a contentious topic. Hong Kong people seldom deny their Chinese roots and they do share pride in being Chinese; at the same time they seek to distinguish themselves, both culturally and politically, from the mainland (such as speaking Cantonese and writing traditional Chinese). In general it is fine to address Hong Kong people "Chinese" on a cultural level.

Furthermore, opinions are very divided among whether Hong Kong should have a close relationship with China or not. Politics is split between pro-Beijing and pro-democracy camps. Some Hong Kong people think every Chinese person should "love their country" (a requirement for all candidates of the head of government). However, some people interpret this as supporting the current communist party. Some people think closer economic ties with China will benefit Hong Kong. Some people think Hong Kong has always been self-sufficient since colonial days. The arguments go on...
