Sorry for the part I didn't get right.
Well, you use very extreme and radical words. You are not hated by zoo enthusiasts. Some people disagree with you, some may hate you, I don't, many don't. The gap between disagreeing and hating is huge.
Then, I believe brainwashing is very subjective in this matter. Antropomorfism is considered an innate tendency of human psychology. A trait very common with regular visitors, people who do not necessarily know animals very well, but also present in some people who know them very well. But I think the more people are into zoology, conservation and animal studies, the less they're inclined to antropomorfism. There is a difference between bad manutention, and "they're better of in the wild". Makes sense, off course they would be if they were wild born. I am not a master of the subject, but something that is omitted when talking about animals is that they're also individuals, they do not have the same background, the same traumas if they have some, and their needs may differ from one another as well.
Also, I do not know everything you have said about zoos, I don't know how bad or well you've talked about zoos in general, but I believe some do a great job, a job that needs to be perpetuated.
