I only found out 2 months ago I've used Taproot
without realizing it. I can't say it's very important
to me 
There is a huge difference between saying that something is not important and that something is not important to you. He didn't say "
to me". Therefore, he's spreading misinformation against Taproot the same way that he is spreading misinformation about the LN. He has never contributed anything to Bitcoin, so therefore this comes as no surprise.
Is taproot important? Not in any functional way.
Pure lie, there is nothing to talk about here.
Pretty much anything you say on this forum has an implied "in my opinion" attached to it, unless it's a blatantly obvious fact, in which case the distinction wouldn't matter anyway.
Your example is particularly absurd. To any sane observer "important" is a judgement, not a statement of fact.
