Yes, let's use MY argument. Because my argument involves using the English language, and in the English language mandatory does not mean you have no choice. On Thursdays, we have a mandatory meeting at work. That does not mean that my boss is going to tie me up and drag me to the meeting, does it? No, that would be ridiculous to even suggest. But if I do not go, there are obvious consequences. The same thing applies to the commandments. They aren't suggestions, they are commands. They are mandatory. If you choose not to comply, there are punishments attached.
