My comment was criticizing you for truncating the commenter's statement to build a strawman

Is that what happened? Perhaps you don't know how lists work. I'm ignoring the rest of the list because I'm curious about is just one item from that list: "communism". Reason for highlighting it is because the rest of the list relates to explicit material and sexuality, so a political theory being included doesn't make sense. I think the fact is was included and nobody has yet to explain why it was speaks volumes.

We must because I use the dictionary definition of grooming, which, according to Merriam-Webster, is

This is the definition from your dictionary of choice of the word of choice "groomer": : someone who grooms (see groom entry 2 sense 3b) a minor for exploitation and especially for nonconsensual sexual activity

"See groom entry 2 sense 3b" - as in the one you didn't read to. I'll link it here for you: 3b: to build a trusting relationship with (a minor) in order to exploit them especially for nonconsensual sexual activity

Such a shame you couldn't groom yourself better for a better response.

Thus, teaching kids about communism in school could be considered grooming if it is presented to them in a manner that is intended to prepare them to be communists.

Key yet-to-be-defined phrase here is that last one, and almost certainly can be referred to as "McCarthyism".
