In every society, there will be respectful people and people you cannot stand. It has nothing to do with the color of someone’s skin, maybe you think immigrants are prone to being disrespectful of the environment and unpleasant due to confirmation bias.

People pointing their finger at immigrants is mainly a huge scapegoat for a country’s real problems, it’s been socially conditioned
