I believe this is the first night they have burned churches. They have been doing cars for 12 nights...thus the 300 number you mentioned.
The 300 number didn't happen overnight either.
They are starting to get bolder and bolder as each night passes. As predicted by some on here and elsewhere.
We probably havn't heard about all the christian churches burned or attacked but you can bet your bottom dollar that if one mosque suffers as much as peeled paint, it will be headline news.
Looks like they are running out of cars to burn.;)
