“What Baptists Say” or don’t say means nothing to Catholics.
There is nothing wrong with working as a dance DJ assuming you are not playing outright dirty music like WAP or whatever. I’m presuming if you are DJ-ing your average wedding with all ages there, people wouldn’t expect you to play that stuff anyway.
However, if you are Catholic and take any job associated with weddings, be prepared to deal with the issue of being asked to do your work for a gay wedding, and look into the civil law applying to your work so you’ll know if you might end up with a fine or jail time if you won’t take a gay wedding job.
