Is this how you convince people that creation is true?

No, I think it's pretty stupid to do that...plus in the end it's not gonna do anything to change his beliefs, unless it's out of fear that they would kill him or hurt his family. It would also just obviously give Christians a bad name, I would like to say that some non-Christians who wants to make Christians look bad do that...but I've met some really really stupid Christians in my life so...this isn't unbelievable at all.
