I can explain: it's not, it's a lie. Using the wrong gender feels wrong but that's about it. It's a common second language learner mistake and it doesn't make you sound like a moron. With a little luck, you took a gender that's accepted in other regions of Germany (like die Email is standard while das Email is southern east I think). It's a mess.
Technically, there are ambiguities but not really like der Leiter the leader die Leiter the ladder and of cause you could find an example where this is really confusing, unless you are a bit patient and have some empathy.
In any case, I have deep respect for everyone who learns the mess that's my native language and nobody should feel bad for making minor mistakes.
