I really don't know where you get your ideas from. I'm pretty politically aware and I've heard nothing of about a growing anti-Jewish feeling. I suspect your source of info is bogus.
Where do you live ? That might hold a clue.
The only 'bastards' btw were German fascists.
The immigration issue is quite another matter. Britain is currently being flooded with eastern europeans looking for well paid ( by their standards ) menial jobs that no-one here can afford to take.
There's been a large Moslem community here for ages. What bugs me is that they
*choose* to be different and simply aren't interested in integrating into our society. This may simply be because Moslem teaching isn't very compatible with western norms. Sooner or later, something will have to 'give'. I have my own views on this based on experience.As part of the EU, our control is now limited.
I do suspect that immigration is likely to become a new 'hot topic' though after years of being simply a far right-wing interest.
