It's not about one's opinion about censorship. We can leave that
entirely aside. Two major questions loom: first, Tor is an
international network.  Sometimes the node operator and the hosting
site are not even in the same country. Whose definition of illegal do
we go by? The Netherlands, Iran, the US, Norway, ...?

Much more importantly, once you start filtering for content at all
even really poorly wrt what you are targeting, you are implying (in
the sense of the law, rather than logic and rationality) that you
_can_ filter content and therefore are obligated to filter whatever
the local/regional/national authorities du jour want you to
filter. (Admittedly this might be more important in the US but not
elsewhere; I'm not as up on that as I might be.)
