Edit: It seems to legitimately be a teen and not an adult with an agenda but many of my points still remain, which I left and can be read after the end of this paragraph. The person who made that Reddit seems to be a teen with an existential crisis, In one of his posts he replies to a question "What life lesson messed you up but ultimately you grew up from?" to what he replies (not his exact same words) "To know there is no God, we are going to die, that the sun will explode and that life's only purpose is to reproduce" That seems to have rocked his world, from thinking of himself divine god like creature to what we really are and the harshness of reality, he became aware of his own mortality and feebleness then he then gets confronted with the concept of zoophilia and bestiality (exposed to it likely due the new tiktok trend of reacting to zoophilia or because of furry), which breaks even more his self esteem as something special. It really hits him hard to know we are not that different from other animals and cannot accept it and so to compensate those feelings of inadequacy and the suffering that causes it he is on a path to fulfill himself, obtain self recognition and seemingly more important to silence all outlets that remind him of such. Those who accept non-human animals to be worthy of human love and sex and thus the most mortal facet of humans that bridge species barriers in a visceral level. Notice the tone of his post, its root cause seems to be all about not being like animals but different. I wouldn't be surprised if soon he takes an interest for hunting.
I don't think they really researched, that probably comes as the most common things said by the zoophiles they have debated. however those points against it are the typical bullshit society spews. Somehow gives me religious vibe the way he talks about biology and the purported difference of humans to other animals. Saying words like "hormones" yet not knowing anything about it, ironically presenting evidence against its own premise by mentioning them. Once again its more because the person against it feels degraded and less than human by the concept of zoophilia and bestiality. "Remind yourself of the difference between you and an animal" That says it all, "we are different and superior" Next time they get a vaccine or any benefit product out of the similarities we have with non-human animals might better cherish the fact we are so similar and appreciate them more.
Also i noticed something concerning. Because the target demographic is teens they are easy to manipulate and more importantly underage, if any serious issue might arise zoos involved will have no chance against the law and public scrutiny. It really makes me wonder about the moral of such person, exposing teens to sexually explicit material and using them.
Example of his manipulating nature. Isn't it curious how after mentioning furries and then guidelines for crusading there is list of guidelines about what to do if you think to be a zoophile? But the real intention is; after he poked the furry hive he made a faint almost subconscious link to zoophilia making them and their haters aware of that, he reassured them to be separated, he then turns to a beneficial and impartial looking facade. This is another manipulation tactic to obtain more supporters, specifically furries, because a significant amount of furries will have zoophilic interests yet are still unsure and feel "dirty" when reminded of that and so feel compelled to join his crusade against zoophiles as a way to give themselves moral credit and feel right, show to themselves their haters and others within their group that they are not zoophiles but the contrary, it is because of zoos they have a bad reputation! they think. But at any moment when the furries no longer are desired they will turn against them, a group of "EpicGamersAgainstFurries" will form.
