You're being downvoted because of your argument from intimidation ("no self-respecting web developer...") and your wording ("such an insane thing"), not due to a lack of understanding browsers.
No, tell the truth - just don't be a fucking asshole about it. Everything about the way you're talking makes you sound like an aggressive jerk. Even your username screams "I'm an asshole who thinks he knows it all and always has a snarky reply ready". It's OK. We've all been there. Exercise is a good way to get the negativity out.
