Huh? I'm a dummy--teach me this arcane English rule that i wasn't aware of until now. For what it's worth though: Have you always held such righteous standards for dialogue? Hard to follow what people are saying when they (oops!) speak with the wrong perspective? You must struggle in the modern world, the way people eviscerate our language publicly pretty much 24/7. I'd feel bad for you if you seemed like a decent person.

As opposed to arguing about fake rules that don’t even exist in modern English, maybe just apply the slightest bit of logic. Language doesn't work the way you are insisting it does, it’s not math.

No, you dummy. The reason we use "are" with "you" is because it was originally plural. However, language is mutable and ever-changing. You is almost exclusively used as singular now, yet it keeps the plural "are". The point being, your statement that "they is" is wrong doesn't prove anything. We use the "wrong" grammar for words all the time and we don't care, until you can do it to hurt someone.
