"We only oppose *illegal* immigration"

I'm getting sick of hearing this. If your only problem with illegal immigration is that it's illegal, then you should be okay with all immigration if the government adopts an open-border policy. All immigration would then be legal, and you wouldn't have any illegal immigration to worry about.

But no, if the government were to adopt an open-border policy, the anti-"illegal" immigration activists would probably be very pissed off.

How about this: rather than immediately abolishing all borders, let's just remove all immigration quotas. Give a visa (for FREE! or at least a very very small fee) to anyone who requests it and turns out to not be a violent criminal. That way, anyone who wants to come here and work can come and work, and there wouldn't be any excuse for not coming the "right" way. And as an alternative to deporting people who overstay their visas, allow people to renew their visas after expiration by paying a goodly fine.

Again, the anti-"illegal" immigration activists would still oppose this. What they fear isn't people coming and staying here without the government's authorization. What they fear is a lot of foreigners being here.
