It doesn't. He's as much of an asshole as Cathy. Well, maybe not. At least he believes in the American ideal of equality.
Cathy expressed his opinion about marriage to a reporter for a large Christian publication that directly asked him for it.
Smith drove up to a drive through window and blamed the random girl that was working in it for the opinion of the owner of the company with the intent to publicly humiliate her, even though she is constrained by company policy form expressing her opinion.
The only wan you can possibly think that Cathy is the bigger asshole here is if your morals are so fucked up you think it is a good thing to attack people who can't fight back. This is the same thinking that leads you to blame the victims of rape because they dressed in the wrong clothes, or were drunk, or maybe were hanging out with the wrong people. Before you know it you will be thinking children actually enjoy sex with adults because they are all a lot more mature than they let on.
Keep up the good work.
