Just a reminder:

Post Kitzmiller the Discovery Institute threw their old allies, they Young earth creationists under the bus because they had to.
They are not Young earth creationists, they are old earth creationists, and they’ve also had to retreat on evolution as well, acknowledging that micro evolution takes place.

So if you are arguing against old earth creationism you are shooting a bit off mark, it’s now just macro evolution and our descendancy from primates that DI is trying to overturn.
