How does moderation decide what to remove? What do you do if you see a perfectly reasonable comment in the modlog?

I was going through the modlog today and found that this comment posted to lemmy.ml was simply removed for being "reactionary".

Removed Comment What reform of France's educational establishment would satisfy you? Should they move their weekends to Mondays and Tuesdays in order to avoid accidentally aligning with any religious practice's day of rest? This is a ridiculous standard to hold any societal institution to. Because France's dominant culture has been Christian for many years, its secular institutions of course have echoes of Christian practice within them - but this is not proof that they are Christian institutions. Education is good. Education should be given to every single person in society, and every person in it should have a right to receive a full secular education regardless of their parents' opinion on the matter. And during the course of that education, class, ethnic, and religious differences between children should be minimized in order to socialize children into being tolerant, metropolitan citizens. reason: reactionary

That sounds like a perfectly respectable position to have, even if it may be a little controversial, but it is more constructive than divisive. I really like lemmy's transparency in showing what was removed and why, but for the first time I'm seeing what looks like a summary removal of an urbane comment.

Am I the only one who is worried by that? Am I missing something here?

By the way, I'm not interested in debating the subject, there is plenty of debate in the original post, what I want to know is how any of you would frame this as decisively reactionary enough to throw out of a healthy debate when comparing with the flood of shitposting we see every day that doesn't get struck down.
