If our country was formed by the backs of hard working slaves....then why do we sent aliens back?

Slavery has nothing to do with immigration, however I'll have to say I'm for all immigrants legal or illegal, I love how people say, they need to go back and work hard in their own country and better their country,, WHY? did our ancestors do that??? I'm pretty sure our ancestors fled their countries for freedom religious freedom corrupt governments, or just the simple fact that they didn't like it there and they wanted to go to the new world,,, how dare we as americans tell another race to go home and fix their country when we know damn well the only reason we are here is because our own family couldn't hack it and fled here to steal land that WASN'T theirs, but of course we don't care because we are benefiting from it!!! most of the people who answer on here are racist, that's all there is to it, they personally have not been affected by immigrants, actually they themselves are immigrants, well not really they are more like mutts, since they have so many races in them they don't even know who they are, yet want to kick out people who do know who they are, oh and another thing i love is how illegals are murderers and rapist etc... really??? americans are too!!! we should send americans who commit the same crimes to prison in russia or just send them to cuba!!!! The crime is of the person not the race or culture..... I am a typical american woman 100% and I'm saying BRING ON THE IMMIGRANTS, everyone complains that immigrants are stealing their jobs, really? because the last time i checked we as americans DO NOT want to work hard, we want the fab life with the cushy job, where we can work for less but more pay,, everyone says they steal are jobs, but i havent met a person yet who can say that 100% an immigrant stole his or her actual job....
