I don't really think that the other Gems could be corrupted at all, they probably shapeshift in the species they're guarding so they would trust over them (Ex: In real life, people sometimes use masks to deceive animals so they can help them). But if some members of their species are on Earth, it's GAP's job to destroy anything that's a threat to humanity. This would lead to conflict with other Gems because they endangering their protected Gem animal species, it could explain why Lapis didn't trust the Crystal Gems. So GAP could see them as a threat due to their appearance and followers, but in actuality, they're not.
