It seems like, for various reasons, you want to make a very public statement.
In case it is not 100% obvious, I'm quite unhappy with the situation (having a TA shortage, and having to run the class this way).
Having said all of this, happy to see a healthy discussion in Ycombinator. I'm a big supporter of free speech, and I think there are a lot of interesting comments here. So more power to you.
