The common misconception out there is that every comedian is going to be very crude overall. While it is true that there are a lot of comedians who enjoy vulgar language and jokes, there is also the option to go with clean Christian comedy as well.
When dealing with a comedian who is also a clean Christian, there is no chance of there being some very cringeworthy situations. This means that families have no issue bringing their young children to performances. In fact, this is one of the major reasons why so many people hire these types of comedians over other options. A family friendly event needs to have a family friendly comedian.
Even if they are considered Christian, that does not mean that every joke is going to be religious. This has more to do with just the overall cleanness of their routines.
