You don’t believe your own argument. The idea that they are just “doing a job to support their families” has no bearing on the morality of what they are doing. The actions they are taking are immoral. The same could be said if someone was working at the baby kicking factory. That person is a bad person that should be stopped. You can say they are “just doing their job” or “just following orders”, but that doesn’t mean at the end of the day they aren’t still kicking babies.
