If not, please explain your point. (How do people misinterpret those verses?)

Joking?

I thought it was "take literally", not "misinterpret"

Okay, I'll play along.

The kingdom of heaven is -- literally -- like a mustard seed. (It's only if you remove the word "like" that the literal interpretation is problematic.)

As for the second verse you referenced, I see no problem with taking it literally. Obviously, beyond the narrow, literal meaning, it has wider application.
