I was part of a group of friends who made plenty of gay jokes as we thought they were simply funny. However, one day, my wife pointed to someone who seemed to be gay in our circle and so, we stopped making jokes. I remember that my friends and I weren't homophobes in that we bought into the idea that they were born that way and, unfortunately for them, they simply weren't allowed to have sex, ever. So, we didn't avoid them or even feel uncomfortable around them.
Today, I realize that the amount of jokes we were making probably did hurt closeted gay friends that we weren't even aware of. There is no such thing as "gaydar". Some even get married as hetero trying to fight what they are.
Being raised as a JW is already not ideal. Being gay and raised as a JW or any anti-gay religion is absolutely horrible.
