(Replying here cos of depth limit..)
I thought you handled it pretty well tbh , and I really have the same problem and struggle to just let cuntish behaviour go unchallenged :P
Seems I've pissed off a spammer today cos of that, but it worked out and I just got a trending post out of my annoyance lol
I don't think I did handle it well at all. With the guy who got upvoted with a voting trail, my second response was rather the rude. And to the nihilistic one accusing me of being a coward, I didn't even leave an invitation for another a response. There's only so much you can do. I go into a the conversation with the right state of mind, being able to retain it is difficult if they didn't also enter it with that same sentiment.
