I'm not JW, but I spend some of my free time looking things (anything) up online. I doubt we can judge such a large group of people, but we also can't say there isn't anyone out there that fits your description. Though I'm not sure what you mean by people that spend hours looking at wrong information on your faith, I think most of them are trying to get information and don't realize what they're reading isn't true. There's a lot of great factual and/or official websites out there, but there's also a lot of sites set up by someone who doesn't know what they're talking about or presents their thoughts as facts.
I spend quite a bit of time reading articles on things I find interesting, but I don't idolize them. I just want to know what's going on in the world and understand what I'm not familiar with. There's plenty of people who go to the internet looking for answers and get fed the wrong information. Researching is easy to get caught up in, too, especially if you feel passionate about or intrigued by it. They may very well worship God in their own way but spend some time learning (even if they're misinformed) about other religions (or anything else).
I wouldn't say someone who spend hours trawling the internet, reading false information about history worships history. It's just sad that their time wasn't better spent learning actual facts.
But then again, your definition of idolization may differ from mine. I define it as putting it above everything else, before God. I don't know how different that is from your definition.
