I think there is a disinformation campaign against Hong Kong people here at mainland (Actually, this should be "in fact", not "I think").

During the Umbrella Movement, I asked around for people's opinion, many believes HongKongers was seeking for separation rather than democracy. One thing that makes such disinformation campaign easy, I think is because the slogan is not hitting the real goal. It could be more clear if something like「我要真民主 (I want real democracy)」is run a long side with the slogan「我要真普選」. The key is to leave no gap for those disinformation campaigners to operate.

Also, 蝗蟲論 (https://zh.wikipedia.org/wiki/%E8%9D%97%E8%9F%B2%E8%AB%96) is very harmful. Many of my family member, even young ones believes "HongKong people thinks we are locusts". I personally view this objectively (In short, "Then why you go there and brought all of their milks?"), but many people don't.

Communication is important, you know. The two side must understand each other better so the common goal might be reached. Don't be fall to the trap and got Divide and Conquered.
