Of course they do. There's a reason kids today still use phrases like, "That's so gay," in a deragatory fashion. It has nothing to do with upbringing, and certainly nothing to do with what they see in the TV / movie / soundbite culture that surrounds them and, rather, tries relentlessly to brainwash them into "normalizing" homosexuality.
Kids know naturally, instinctively, that there is just something sick about a man pushing a penis into another man's anus full of sh**. It's one of those things nobody needs to teach, and it is why homos instinctively feel ashamed of what they are and what they do, and why they suffer the tears of a clown as they march with fake smiles in fake "pride" parades.
