Are you conflating illegal immigration with legal immigration?
I know the left likes to equate terrorists with Muslims (e.g., the Right wants to stop terror, the Left asks why so racist, apparently assuming all Muslims are terrorists since they equate opposition to terror as opposition to muslims).
The Left also equates criminals with blacks (e.g., the Right wants to stop crime, and the Left asks why so racist, assuming all blacks are criminal thugs).
Maybe you are doing the same thing with immigration??? That seems to be the only sensible explanation for your post.
