Trolling: Where do we draw the line?

I find myself constantly questioning where the line is drawn when it comes to tolerated trolling. Take today, for instance:

Up until that point, the discussion was entirely free of ad hominem attacks—if you ignore a bit of labeling, even from the moderators. Then, out of nowhere, some user jumps in, misquotes their opponent, and tries to discredit them based solely on how long they've been active on the site. On sites like Bloomberg or The Wall Street Journal, this kind of rhetoric usually isn't permitted, but lately, it seems the mods are just looking the other way...
Can someone please define whether this type of provocation is acceptable here? I need to know if I should bother responding, or if the moderators will step in to preserve an actual argument-based, civil discussion...

Honestly, I’m kind of scratching my head here—seeing you, as an entrepreneur, actually acting stoked about these new tax hikes feels a little surreal. I guess it makes sense why we're all looking at you sideways, right?

P.S: Sorry for drifting a bit off-topic.

Henry Hernandez7 said:I’m also surprised that you, as an entrepreneur, are celebrating these new taxes. Why is it so strange that we're questioning you?

The odd thing is that I’m not actually celebrating any new tax hikes—I'm just weighing the pros and cons. It’s certainly not as if I'm some Marxist or communist, despite what certain forum users insist on labeling me for no reason. A bit of skepticism would be fine; everything should be open to civil debate. The issue is that some people seem determined to derail any discussion the moment someone presents a non-mainstream view or refuses to reflexively curse every single change...🤷

I'm not some sensitive soul who collapses at the first sign of an insult; I'll manage. I just can't decide whether it's worth engaging with the trolls or simply ignoring them. I don't usually resort to personal attacks, but I suppose I could if the moderators decide that level of discourse is permitted here. Hopefully, a moderator will weigh in eventually...

My apologies, file, I haven't seen this yet
