I think I'm going to try to put my wife in a fighting class
Why would you put her in a fighting class?
I'm sick of seeing her getting beat up by a bunch of whores
You shouldn't make your wife do something she's uncomfortable with. You should respect her wishes.
What if these classes teach her about self-confidence, and in turn it makes her better at life?
It's great you are looking out for your wife's well being, but I believe she should choose to go on her own volition instead of being forced to. if she wanted it herself, she would enjoy it a lot more without the pressure.
