I'm a person on the right and I have always thought you need to have a path to citizenship for the people that are here. In general I don't have a problem with Mexican and spanish speaking immigrants. For the most part they actually respect America and want to work hard here and try to assimilate. Dreamers should be allowed to stay. Bush tried to get this through when he was President and there was this Senator who went out of his way to not let it happen because he thought the Dems should have their name attached to it. His name was Obama. He was not the only one but check the voting record and you will see he voted no and did a lot of work behind the scenes to squash the effort as was published in a WST Journal article recently.I think your points are fair. Your third point is in effect now and has been in effect forcefully since 9/11. I think the first point is what everyone would want. However, reality makes this so difficult. Even building a wall across the entire border does not accomplish much. There are tunnels controlled by the Mexican mafia all through out the border at this point in time. I wish we had some way of securing it. Hopefully, technology will advance to the point this can happen. But it is not reality at this time.
I do not understand why the fourth is an issue. However, it is. People on the right do not even want kids who were brought to this country illegally with no fault of their wont become a citizen. These people are American in culture and in every way but documentation. I know an American couple who brought an infant from Uruguay to the US illegal. They never formally adopted her because they brought her in illegally. When she was 18 she wanted a driver's license and SS number. When she applied, she was caught as someone who entered the country illegally and was facing deportation proceedings. This was at least a decade ago. Thankfully, this was worked out with some legal fiction. These are incredibly difficult issues.
But, the hysteria about sanctuary cities and states is overblown. .
Unfortunately getting things done is our problem because both parties want to take credit for it instead of just getting it done. I'm all for Pirata's points and I'm a conservative. But after offering a path to citizenship we can't keep doing that. It happens once and we tighten things and actually enforce the laws including deporting illegals that break the law which is not happening now at a high enough rate and some places enforce it and others do not.
