When people talk about their opinions on immigrants, the first things that come to mind are: they steal our jobs, the men are violent, the women are promiscuous, and their children are a bad influence on our kids.
This may be because the changes immigrants can cause can be very sudden and challenging. To go a step further, it may be even natural, because every animal reacts aggressively when unknown individuals from the same species approach their territory.
So I think it is may be a natural reaction, but people should not keep this mentality because we are human and have the ability to think logically. The first point is that they don’t steal our jobs. They are nothing that can belong to anybody to begin with and people who have lived in the area for a long time don’t want to do certain jobs like rubbish collection etc., so immigrants only try to benefit from this situation.
Besides this, because they are individuals just like the long-term residents, not every immigrant is violent or sex-crazed. So there may of course be immigrants who kill people or prostitute themselves to get some money, but them being immigrants is not the main reason for that.
Lastly, immigrant children are not a bad influence on the other children. The behaviour of the parents can have more of a bad influence on their offspring than the immigrant children themselves. The children of parents, who genereally dislike immigrants, would come to hate everyone different from them without trying to learn or accept anything about them.
Why do people discriminate against immigrant children in the first place? There are fewer and fewer children in so many countries all over the world, so we are in need of those children to support our countries in the future.
And as to why people are afraid of immigrants, I think it is because people who are affected by their presence cannot be bothered to take the second step to think about this topic logically. This may be because they react too emotionally, but in my opinion that is still no reason to discard the human ability that distinguishes humans from animals.

I agree with you. Especially Japanese people tend to afraid of immigrants, I think. As you mentioned “every animal reacts aggressively when unknown individuals from the same species approach their territory”, I think Japanese people over reacts on immigrants. Because Japan is an island and we don’t have a close relationship with other country in geography, Japanese have a strong connection of being Japanese. So, whenever they meet with immigrants, they instinctively afraid of them.
Also different language and culture may related to feeling of “afraid of immigrants”. Because many of immigrants have a different culture back ground and language, Japanese cannot understand. If people can not understand well, people tend to feel “SCARY”.
Therefore, if people get to know each other the feeling of afraid of immigrant may ease.
I strongly agree with you. Especially these following sentences you wrote;
“every animal reacts aggressively when unknown individuals from the same species approach their territory”
“So I think it is may be a natural reaction, but people should not keep this mentality because we are human and have the ability to think logically”
As you mentioned “change” is feaful and demanding. What is important is to see themselves as they are.
