So naturalized citizens can be deported whereas a natural born american citizen cannot.
> Should legal immigrants, especially naturalized American citizens, be harassed by the government?
Don't remember saying they should.
That's misleading.
A "naturalized citizen" who is proven to have fraudulently obtained citizenship, and therefore deportable, is considered to never have legally become a citizen in the first place. So this person would only have been a pretend "naturalized citizen" on the surface, and by the time they are deported they are not considered to be a naturalized citizen.
A real naturalized citizen, who legitimately obtained citizenship, cannot be deported against their will, no matter what they do after becoming a citizen.
So a naturalized citizen cannot be deported. A person who pretends to be a legally naturalized citizen but really isn't, can.
This is all in contrast to non-citizen immigrants, such as green card holding permanent residents, who can be deported for "aggravated felonies" as well as other specified reasons.

I read it that way, but if that was not your intent then OK.
