How can I come across as a know it all and ask questions at the same time?
If people weren't capable of forming opinions on things they "know nothing of", then how do deaf people assume to know the hearing? How does one study history if they weren't there? How do sociologists study groups otherwise unknown to them? Does this mean that hearing linguists who argue that ASL is a language (which it is) don't know what they're talking about because they are hearing? So I shouldn't believe them? Does this mean Grendel can't make decisions for her daughter because her daughter is deaf and Grendel isn't? Am I allowed to tell you that you know nothing about what's best for children because you aren't a parent?
All I've done is bring my life experiences and education into the forum. That's what people do. It's part of the human connection. I would like to believe that humans are intellectual and curious beings, but that isn't always the case. However, it's the "hearies" like me who help the "deafies" like you, because history shows time and time again, it isn't until a majority puts themselves in the shoes of the minority that something changes.
For example, I don't know what it's like to be discriminated against for being deaf (though I do know what it's like to go through life unilaterally deaf) but I do know what it is like to be discriminated against for having epilepsy. I may not like some of the unintended consequences of the ADA, but it doesn't mean that I don't understand the legal components. I may not agree with parents who use oral only, though I can see how they'd be convinced it's the best route. If you can't step out of your own shoes - or ears - for a moment, you're not really productive.
What makes humans so incredible is the fact that we "get smarter" over time. We build on old information to find new information. That's what intellectualism is. Maybe intellectualism isn't your thing? Because if that's the case, then you're no better than the "hearies" who can't for one minute believe that ASL is a real language, or that the deaf aren't stupid, or that English is superior.
All I've done is shed light on how some other people may think and why. If you don't understand the whys of things, you'll never be able to change it.
Think of it this way: If your computer has a virus, do you shake it and yell? Sure, but is that productive?
