If we include bannings because of the discussion on INGO, then there absolutely HAS been that 'violence', even on INGO....Heck, here on INGO alone there've been a HUGE number of Islamic-heretical posts. Yet, no violence (that we know of) has erupted.
It has been long been well known, and well established (even in this thread) that one may discuss, debate, denigrate, and 'bash' one of the groups, but doing the same to the other group will absolutely cause a thread to be locked, and members to be banned. The double standard is just as hateful as the attempted actions of the two scumbags in Texas. Just another form of terrorism, a different way to 'fight for the cause'.
The disparity is striking, and well-noted. That disparity will, ultimately, likely lead to some problems, perhaps legal problems, for the forum.
