Welcome, JWINQUESTION!
I am an open-minded Christian. I doubt you will see me use obscenities, online or offline. But for a few minor things, my lifestyle is not significantly different than when I was a JW.
If two people are in a committed relationship, whether same or of opposite gender, how would that lead to an increase of STDs? As for myself, I’m not going to marry anyone of the same gender, but then I am not inclined to do so. What other people decide to do is their business, not mine.
