No matter how strongly you feel about something you still must do it the right way.
If you're going to have a country you have to have borders along with laws to protect those borders.
Anyone outside of either the border or the laws concerning crossing over into the opposite side shouldn't reasonably expect an exception made on their behalf just because they feel they're doing no one harm by entering to do work or wanting better for themselves or their families.
When I came out of high school I had to work to pay my way through college, I couldn't just sit down I had to go through a process to have a seat reserved for me and yes at the time it seemed expensive but, that's a part of the process.
I think with illegals that we see today they don't get that concept of laws and process.
