I hate to defend BE but in this case it is pretty clear what point he is trying to make: he is deliberately using the same arguments and the exact same phrasing that many leftists use when defending people who join the US military. BE has had a long standing beef with leftists who defend US veterans.

He has made it very clear that he doesn’t agree with making excuses for people who, for whatever reason, choose to become soldiers for the US empire, and he is drawing a parallel between them and ICE, pointing out that if you think working for ICE is indefensible you should also think being in the US military is just as irredeemable.

Whether he is right about that is debatable but clearly that is the point he is making here.
