It's extremely hard to take this comment seriously when everything you fault Tyson for could easily be launched right back at you.
You call Tyson "a pedant" because he tweeted saying "Leap Day" was a bad word choice. But you are also saying the post you replied to shouldn't have the word "cheesy" so doesn't that make you a pedant as well?
Sure, your point is not simply that the word "cheesy" is bad - you're going a bit more in-depth and trying to make a bigger point (specifically that Tyson is harmful). But Tyson is not simply trying to feel smart by saying he doesn't like the name "Leap Day" - he's also trying to make a bigger point (specifically, he's teaching/reminding us that our concept of a year is based on our planets orbit, not an arbitrary number).
Similarly, you comment that Tyson "gives the wrong idea of what acting intelligent is" but did you notice that you said "intelligent" instead of "intelligently" despite the latter being correct? Aren't you giving the wrong idea of what acting intelligently is to the youth by making gramatical errors that the fragile youth may mimic?
Looking at someone under a microscope, as I have just done right back at you, is not the best way to judge them. Your typographical error will not hurt "the youth" just like Tyson starting a tweet off in a clickbait style with "The Leap Day is misnamed" won't hurt us either.
