How is it a double standard? Show me a time when anyone has criticized a group for rescuing civilian hostages in an urban war environment and causing civilian casualties along the way (with an unknown percentage of those civilians actually supporting the hostage taking, an issue you clearly don't want to even mention). You can't. You’re lying about the double standard. The only way to discourage hostage taking is to conduct operations such as Israel's, whatever the cost.
If people adopt your way of thinking, you're only incentivizing more hostage taking. Which means you might as well support hostage taking. Despicable.
