Fair, but most controversial doesn't always mean most important. Usually, the narrative is something like "All the hard slogging that this movement has done has been awesome - it's changed society for the better. But now they're overreaching" - I can see that aligning(seriously, not just for rhetorical weight) with a belief that the group is really about the sloggy stuff, and the goes-too-far stuff is just a novel addition that isn't core to its beliefs. That seems to be what Aaronson meant, and also most others I've seen use similar phrasing.
