There may be an age or generational explanation for this, but I especially notice this behavior on Reddit while not nearly as much here on Lemmy (though maybe that’s also a mater of implementation).
It seems many are so quick to assert overly-confident positions, but then hit-and-run with some smarmy remark at even the slightest challenge, then quickly block. Like, not even crazy stuff. Just basic, civil disagreements. I can pretty well predict when it will happen, and it always feels like such a petty ego-sparing fingers-in-ears denial thing to do, and to me if anything shows they were not very confident in their views being challenged.
I think I’ve only blocked a handful of people over a decade who were actively spamming, stalking, or spewing extremely hateful rhetoric and I just reported them simultaneously. You have to cross a pretty extreme and irrational line for me to do that.
The reason I ask is to see if I’m missing something; to better understand the mindset of those who do.
I use user notes for this - notes like “argues in bad faith,” “is knowledgeable about x,” etc. Then if I feel talking to someone is a waste, I still get their input if I want it but know whether or not to engage.
I use multiple devices to browse the web. Those user notes don’t carry over. So I just block people that argue in bad faith, those blocks do carry over, makes things easier for me to ignore, and prevents me from falling into the trap of debating those shitheads.
