There are many ways in which I prefer IRC to Slack, and I agree with Sir_Cmpwn's general premise that some of Slack's features are more trouble than they're worth. (Slack's threaded replies are definitely one of them, and while I've seen better implementations in IRC-like systems, "just don't thread replies" is so far the best implementation I've seen.) But the problem you're describing here is arguably one of Slack's advantages, not a disadvantage.
