There is a very thin line between supporting the concept of Islam as a personal religion and espousing the violent overthrow of legally constituted government so that the tenents of Islam become the law of the land. What I heard on the video was that the members of the various groups believed that "democracy" was bad because it was not based on Islam, and that they were "intellectually" supportive of, and in favor of, anyone who acted to change the present British government, by violence as opposed to by "democratic" election, into one based on Islamic law. I just never heard them actually say they had done anything or actually encouraged anybody to do anything. (But they all had wierd accents. When are the British going to learn to speak English?)
Because I do not know, and do not want to look up, British law, I cannot say if the things they said violate British law. Because IANAL and all those other disclaimers, I cannot say that if they made those statements in te USA they would not violate federal treason/insurrection laws.
However, I am convinced that those persons are dangerous. They need to be watched, and they need to know they are being watched. I don't think there is any need to try to "entrap" them, as they are most likely to cross the line by themselves without any help from "us."
What amused me was the conversation about going into the 2,000 mosques in Great Britain to teach the Moslems about democracy, and the response that "they" did not want democracyt but wanted an Islamist nation.
I've got a small news flash I'd like to share with all Islamists/Moslems/True Believers around the world - neither Great Britain nor the United States are "Islamist" countries, so if you want to live in an Islamist country do not come to either one. A second news flash worth sharing - if you want to live in an Islamist country that has running water, flush toilets, electricity that stays on all day every day, and great welfare benefits for those that cannot get a job paying $250K without a grade-school education, go build all that infrastructure in some existing Islamist country. Do not come over here (USA or GB) to get all the benefits and then demand we change to suit your desires.
I'm going to go wrap my head in duct tape and take some more meds. Maybe I'll be calmed down by lunchtime.
stay safe.
