Very good comment all around, I just have a nitpick to this section:

Lastly, there’s a very troubling thing I’ve noticed the majority isn’t willing to talk about: there are so, so many people out there who are attracted to kids. Not prepubescent kids, but very few 14 to 16 year old girls will not have had men approach them with sexual comments. The United States of America voted against making child marriage illegal. The amount of “I’ll just fuck this behaviour out of her” you can find online about Greta Thunberg from even before she was an adult is disturbing; people with full name and profile pictures on Facebook will sexualise and make rape threats to a child because she said something they didn’t like. There’s a certain amount of paedophilia that just gets overlooked and ignored.

Even worse, those people aren’t included in research into paedophilia because of how “tolerated” it is. The ones that get caught and researched are the sickos who abuse tens or hundreds of children, but the people who will marry a child won’t be.

This is actually called hebephilia/ephebophilia which is in the general public treated very similarly and often subsumed under the term pedophilia. It is considered it's own thing though. To quote Wikipedia:

Hebephilia is the strong, persistent sexual interest by adults in pubescent children who are in early adolescence, typically ages 11–14 and showing Tanner stages 2 to 3 of physical development.[1] It differs from pedophilia (the primary or exclusive sexual interest in prepubescent children), and from ephebophilia (the primary sexual interest in later adolescents, typically ages 15–18).[1][2][3] While individuals with a sexual preference for adults may have some sexual interest in pubescent-aged individuals,[2] researchers and clinical diagnoses have proposed that hebephilia is characterized by a sexual preference for pubescent rather than adult partners.[2][4]

My guess for why it is more tolerated than straight up pedophilia is that they have reached a more mature body, that shows some/most properties of a sexually developed person. So while it's still gross and very likely detrimental to the child if pursued (depends on the age in question, 16-18 is pretty close to adulthood), there seems to be more of an understanding for it.
