I try to engage with people courteously and not dismiss them because they may have views different than mine. But when people just troll and stuff discussions with unrelated photos and memes, it just clutters up the sharing of ideas. It's like trying to have a serious discussion with a bunch of people but there's somebody with Tourettes who randomly blurts out obscenities or hogwash or irrelevancies. It disrupts the conversation.
The only reason I actually posted that I was ignoring Rome is because I wanted him to know that because of this "digital Tourettes" (so to speak), I will not see anything he posts, even if it is about ebikes or photos of where he rides or how to fix a brake or or any thread he starts, or whatever. Even if it is his honest opinion about something. All because of this weird need he has to disrupt discussions. It is a scream for attention, but it drives people away. That's why I informed him and said, So long.
