That's the point of linking comment threads, so you can see the context and read between the lines. One of those threads, their own replies remove any ambiguity of their meanings.
And the reason those linked to the parent is simply how lemmy (vanilla, at least) works when copying a comment link. At least without fuss. And I'm on mobile.
But whatever, there's plenty of context just from the original links I sent. I really don't give a shit if it's not wrapped up nicely enough for you. I quickly provided counter examples from comments older than his without even trying to find them.
