Do you think that using an anti-terrorism statute in the UK to arrest someone who yelled 'Nonsense!' is appropriate?
Do you think that using an anti-terrorism statute in the US to arrest someone who is a public nuisance is appropriate?
If the answer to either of the above is yes, then we have a deep seated basis for disagreement.
If, however, your answer to the two questions is no, then it turns out that there isn't any argument here.
