I'm going to interrupt a speech
I do not understand the reason for your thinking. What is the reason for the interruption?
Nothing, I just like to interrupt.
You should remain quiet when someone is trying to give a speech. Interrupting would be rude.
Just say I'm a bad person and hate America.
If you respect others they will also show respect to you should you one day be giving a speech.  How about you just listen then you can provide an appropriate rebuttal.
