Regarding the "unimaginative" comment: OP might have just meant that we are in the very early days of artificial meat and dismissing it now would be tantamount to dismissing the internet in the early 90s.
You might be taking this a tad bit too personal. OP described how your argument sounded to them. They didn't condemn your entire personhood because of it.
It's a personal comment about my imagination. How else am I supposed to take it, if not personally? If the OP didn't want me to take it personally, they should have not made a personal comment.
