Because people like to connect with other people and share anecdotes about their own life. That’s human nature.

A man can say he spent the weekend with his husband camping in the woods and how it reminds them of a poem.

A woman can say her wife is picking her up after work and they’re going to a bookstore to pickup the newest book in a series.

These are innocuous statements and yet some states/people would vilify them.

It’s an excellent question.

One would think that reflection of the impact of literature on ones personal life is an important part of analysis.

Also that teachers should be fully and authentically present for their students, not just glorified YouTube lectures.
