Jax,
I dont know you, I dont know anything about zombie mod and I dont play it. Since the punishment you chose was slapping I assume it was a minor offense.
Regardless of the incident, your approach here is wrong. Your status as an admin already overpowers the player. Calling him a fag and bitch DOESNT help you. Nobody will judge you without evidence.. Calm down. You are making yourself look bad even if you had no fault in this..
