Un-scrunch your eyes.
I said no such thing. I think the link you posted is a poor example showing people on FR that are anti-legal immigration and I admit I chose my words poorly in my original response.
The topic of the thread you posted was worker visas. Citizens and legal immigrants whose jobs would be at risk because of an increased supply of legal immigrants have a legitimate complaint.
Speaking out against a political method to increase the supply of legal workers has nothing to do with a persons beliefs towards legal immigrants...but rather their belief that increasing the legal worker base will decrease their pay...it's economics.
