You don’t understand. Judaism isn’t like Christianity. Whether you are Jewish isn’t about what you believe. It’s about the rules of a legal system called halacha.

If you’re born to a halachically Jewish mother, you’re Jewish, and nothing can undo it, even if you go to a Reform synagogue or abandon the religion.

If you’re not Jewish, and you convert under Reform, you’re not halachically Jewish because you didn’t convert under halacha.

May I humbly suggest that you read the Wikipedia page on halacha (if not something more substantial)? Then you will have the information you need to discuss this.
