What exactly are you trying to prove here?
I know they are not paid, but they still have authority on this site: is it too much to ask for them to reply politely, especially to a user that took quite some time to share his understanding of how data will be affected after this sale?
I don't think we need to resort to this bullshit Karen name-calling, especially when it makes zero sense
I don't think, "I'll thank you to not just make random threads when you don't actually know anything." is even particularly rude, personally, it's like the slightest hint a rebuff in it, and certainly not worth making a stink over it. I've made comments like this as a server when people made a rude remark and I've yet to get in trouble over it nor even have it significantly impact my tipping. Most people just go "oh, yeah, I was slightly rude there" and move on.
But to your general point, no, I don't think after the thread this has been and the things I've seen that I can assume good faith on every seemingly innocuous interaction and I care little for tone policing. I called someone a Karen as a joke because I thought they are being overly dramatic about the unprofessionalism of a nonprofessional person over a faux pass so minor I could get away with it at my job.
If the person in question is operating in 100% good faith, then they can take a little ribbing and get used to the idea that, no, this is not a professional environment, no, the mods do not have an obligation to be unconditionally respectful without a hint of reproach to any poster without even a hint of sardonicism, and no,
I especially don't have to do that because not only am I not a professional, I'm not even a mod and I won't ever be one. I'm just a regular poster, part of the community, and I like to shitpost where the absurdity of the situation warrants it.
