I’ll copy the response I used when someone else responded the same way:

Sometimes they run out. Or are 2 hours away. Or are in a bad part of town. There are tons of reasons why someone would be desperate enough to steal food.

Nobody’s encouraging it. All we’re saying is this: as a direct result of the deficiencies inherent to our society and the socioeconomic structure it perpetrates, some people need food but can’t get it through legal means. Categorically refusing to make an exception for exceptional cases is implicitly saying that those people deserve to die.
