Olivia Chow isn't smart enough to be trusted to handle a firearm. It would be like that video where the african guerillas give the chimp a loaded AK as a joke - and he hoses them with it.
Most antis know they personally should never be trusted to handle a loaded firearm because they KNOW they are incompetent or irresponsible, or both. They don't like competent trustworthy people like us because we make them look bad. If they can take away our guns, then they don't feel so incompetent or stupid in comparison.
Antis aren't interested in safety - it's a personal vendetta based on envy.
