So are you asking why it is important to talk about this issue?
I think that it is important to talk about it for a lot of reasons. People with different opinions about illegal immigration will have different thoughts about why it is important to talk about.
If you think the immigration is bad, it is important to talk about it because it is having a bad effect on our country. It makes us disrespect the law because we see so many people coming here illegally without anything happening to them. It hurts our economy because we have to pay for the services that these illegal immigrants need. Finally, it makes it so that we cannot control our population.
If you believe that the illegal immigration is not such a bad thing, it is important to talk about it because immigration is a basic value of our country. We are supposed to welcome immigrants and we are not supposed to hate people just because they do not speak our language well or because they are a different color. We are supposed to value immigration also because immigrants are highly motivated people who will work hard to become productive members of our society.
