Another van drives into a crowd in London

[Pat Mustard]

Mosque perceived as too liberal (espousing Islam of the early 1300s) is attacked by rival 'pious' mosque espousing Islam of the last half of the 1200s ??

The dates'd be most likely the other way round. Most of the liberalism in islam came from before the Mongol invasions, not after. If you ever see a liberal mislim they're either out and ot secular or hewing to older traditions.
