I am confused, why were your messages flagged? I disagreed with you, but I didn't see a reason to flag them? Also I don't know how to flag a message, but that's another topic.
It's not flagged now. But yes, way too many people use flags as an "I disagree" button these days. I feel like that used to be very rare (even down-votes aren't supposed to be used that way) and is becoming more common, though maybe it's always been this way and I just hadn't been on HN long enough to notice the pattern until now.
