Yeah, I read it as, "you refuse to do this really easy thing but gladly do this really complicated thing."

tl;dr Pronouns are simple, LotR is complex

Edit: autocorrect

A logical argument should not need to be interpreted other than through its own premises and logic. I know what the post is getting at, but it isn't a good logical argument. The post postulates that if you are capable of understanding and remembering one complex thing (Tolkien), you are capable of understanding and remembering a different, simpler thing (pronouns). However, that argument fails to address the actual problem. It's like saying that if someone can understand quantum mechanics, then surely they can recite something as simple as the Ten Commandments by heart.

The issue for most isn't that they can't intellectually understand pronouns. It is that they don't really care about pronouns, don't want to devote mental energy to the subject, and may even think that pronoun-oriented people are making their personal issues a burden for other people.
