Responding to an online call, protesters assembled in some streets in the Hong Kong Special Administrative Region, and harassed, even attacked, shoppers they thought were mainland tourists. Comments:

For several weekends, some people have been disrupting social order claiming they are battling smuggling. With their faces masked, they have attacked seniors, surrounded women and frightened children; they are worse than gangsters. They will receive deserved punishment.

Some of the protesters have even advocated independence for Hong Kong, which is illegal and against Hong Kong's rule of law spirit. Such ideas belong to only a limited number of Hong Kong residents, and we must be careful not to allow them to cast a negative effect upon politics in reality.

The protesters said they are against tourists purchasing many products and selling them in the mainland for profit. But they have attacked passers-by on the streets, and their deeds make them seem more like gangsters.

Hong Kong people should be more tolerant and open to visitors ... As to some people traveling to and from Hong Kong many times after obtaining a pass in order to ship goods for profit, the SAR government needs to discuss closing the loopholes with mainland officials.

As interactions between the mainland and Hong Kong have increased, frictions among individuals are almost unavoidable. The residents of both need to act rationally. Conflicts should neither be radicalized nor politicized.
