Call from church about being gay?

First of all sorry if this is the wrong subreddit for this. I was on a vacation in Ohio with my boyfriend, and while we were watching TV at about 2 AM a number from New Mexico called me. They told me about how someone from my local church (I'm from Michigan btw) came in and talked about how I "participate in homosexual activity". He started saying some other things but I hung up pretty quickly to hear much else. How would people be able to obtain this type of information about me when I am extremely quiet about my orientation?
