Yeah, that is what we learned in history. We have also learned from the FROBL that anyone who opposes an open border with Mexico is a bigot, and we know that isn't correct.
I have found few people here that support open borders. Open Borders many that anyone can come across at will and it doesnt matter. Most people that are against illegal immigration(in truth we are all) are not racist. However there are some that do have racist motives. Thats just life
I find that those that support the Presidents view are also very concerned about getting control of the sitution at the border. There are very few true LIbertarian open border folks at FR that I have seen
