One country can only sustain so many people. With all the non-English speaking immigrants America wouldn't be America anymore and it wouldn't be fair on us. There's also increased poverty, crime rates will probably go up, etc.

What is America? Open borders do not take away state sovereignty. It's a well known fact that people assimilate in the country they immigrate to.

Those who advocate for open borders can start by openung the borders of their private property to strangers

You cant compare private property to nations.
