This seems entirely standard for that kind of game. Trolls absolutely will try to rules lawyer so articulating points clearly that ought to be common sense makes it simpler to moderate transparently.
What points do you take issue with?
The first bunch are "Would you jerks cut it out" and the rest is "How not to be a jerk", both seem pretty important.
I don't find it condescending because I think I'm not a jerk but I'm aware that a lot of people are jerks.
