Because you’re incapable of articulating yourself properly.
Nah I’m totally joking, by nature I’m quite a pedantic person. Which can absolutely be a flaw of mine, but at the same time, I put a lot of stock in the words people choose to use. Not always, but I often take care about which specific word I use because I want to be as accurate and precise when expressing my opinion, so perhaps unfairly, I expect the same of others.
So when I use the word essentially, it’s because I’m absolutely aware that you didn’t literally say he is crap, but I think that the content of your post absolutely implied that he’s a bit crap. So I use the word essentially, because it’s a clear way of recognising that you didn’t actually call him crap but I feel you implied it/I inferred it.
It’s also my nature to sometimes be overly combative, which I probably was in my last post. So I apologise for that. As long as you know that I ultimately do think you’re articulate and that I do respect your opinion and enjoy reading your posts, I feel like we’re all good.
