Shimshon is quite an inept debater, so I’ll formulate his best argument for him:

Sometimes you are forced to take actions that result in innocent individuals suffering and this law is such an action since it excludes the majority of the Palestinians who are hostile to Israel at the cost of the few who don’t.

Had this been so formulated from the start, without the overgeneralizing racist garbage, it would at least have been debatable.

Although still incorrect. Unlike with the collateral damage from bombings, the damage here is if not entirely preventable, then at least minimizable. Because unlike in the case of bombings, individual cases of those wishing to become citizens can be investigated and certain measures can be used, starting with oaths of allegiance, temporary surveillance and revoking of citizenship if the individual is found to be hostile after all. Hence the comparison with the military actions is unjustified.
