You have the absolute right to testify in favor of yourself and to explain why you are innocent. Failing to do that reasonably suggests guilt.
If you actually believe that, be sure to state so loudly and clearly during voir dire so the court can excuse you from jury duty because you have no business on a jury. Our system of justice is based on the concept of “innocent until proven guilty.” The prosecution must prove guilt. The accused is not responsible for explaining why (s)he is innocent. The accused is presumed innocent.
Please rethink your position.
