At first I thought you meant on Steemit and I am sad to say I did have at least one downvote that was clearly only because I had posted some LGBT content and talked about my girlfriend. The person's profile was pretty anti-gay. I really didn't know what to do about it. It freaked me out and made me madder than I would have thought. In the end I decided to do nothing unless it kept happening and it didn't. So that's good. Still, it was an unwelcome and totally unexpected wake up call to becoming a part of a new online community.
