Stupid remarks about Christianity

I am a Christian and it makes me really mad when "Christian" people on TV (like in this movie) come across as being so over the top that I am not surprised people reject getting converted. Sentences like "I don't dance; dancing is a prelude to intercourse", or "oh, you drive a red truck? Yeah, pretty, but not very Christian!" What does having a red truck have to do with being or not being a Christian?? It's just unnecessary, in my opinion, and really aggravates me.
