Dude. Like... that's a huge reach. Watching =/= doing it. You know how many people watch BDSM stuff, or for that matter, watch horror movies - gore especially - read about murderers, some even glorify them - does that mean they want to kill people? Of course not.
How about forced porn? Bestiality drawings - of any sort? Would you say such porn - or porn in general - might influence people to actually do it?
Well... some studies show otherwise. :https://www.psychologytoday.com/blog/all-about-sex/201601/evidence-mounts-more-porn-less-sexual-assault
"Evidence Mounts: More Porn, LESS Sexual Assault".
And for dolls? They already exist: https://bossip.com/1271977/fair-or-too-foul-lifelike-child-sex-dolls-designed-by-man-to-stop-pedophiles-committing-crimes/
Also, in some places 14 year olds can consent to sex. Just saying. https://en.wikipedia.org/wiki/Ages_of_consent_in_North_America
https://en.wikipedia.org/wiki/Ages_of_consent_in_Europe
Drawing =/= reality. Porn =/= reality. The main reason pedophilia is wrong because a) children can't consent b) it harms children, duh.
Also, what you're referring to is hebephilia.
For a friendly reminder, there are feminists that think boys - 15 year old boys - being screwed by 30+ year old teachers is completely fine: https://www.theguardian.com/commentisfree/2009/nov/29/barbara-ellen-madeleine-martin-comment
