Illegals are not de facto citizens, they are de facto residents.
Citizens can vote. Citizens cannot be deported for committing felonies. Citizens can more easily and legally bring relatives here. No, we should not make these criminals citizens. I have no problem with legal immigration, which we should expand to the point that there is no room for illegals to come as criminals, but crime should never be rewarded.
Muslim immigrants mostly come here legally. We sure as hell don't need even more of that poision.
