@MelGibsonafter4Beers @fightknightHERO building communities is important, but those communities have to be "no-go zones" where the police don't go because the entire community will rise up against them.
Muslims form these sorts of communities all the time. You need enough people to keep the government from raiding and killing you all though (see Ruby Ridge, Waco etc.) but with 10,000+ or so, you'll be untouchable.
All the raw materials are present. All that is lacking is the will.
