One of two of the posts on here border on antisemitic themselves in my humble opinion! Anniebach, I'm with you all the way, you are right to be concerned about rising antisemitism in the UK (along with a fair few others who also show concern on this thread.)
The brick and the graffiti photos are truly horrific. The fact that many congregations of many synagogues feel the need to post guards outside their places of worship, or places where bad mitzvahs are taking place speaks for itself. I have visited a number of synagogues and a number of Jewish museums across Europe and often seen guards outside, I'm troubled that Jewish people now feel the need to do this in the UK. Antisemitism was a huge problem in mainland Europe in the recent past, hence the holocaust, but Britain was considered a safe place for those who are Jewish. How sad that British Jews feel they are no longer guaranteed here.
