I'm going to kick a homeless guy off my porch in the snow
Why would you kick him off when it is snowing?
I live in my family house, I can do what I want.
I understand why you might want to do that.  However, in this situation it's better to call the authorities and have them deal with the homeless person, as that's a less dangerous solution both for you and the homeless person.  Just kicking him off into the snow could cause him to freeze to death since he has nowhere to go.
I'm going to call the cops, you know what I mean? I mean, he needs to go.
I think that that is the best route to go.  Calling someone like the authorities can help both parties because it can help the homeless person find a safe place to go as well.
