25 years ago, I would have had no fear saying "I am jewish" anywhere, except maybe on the rare occasion that half a handful of skins gathered somewhere and called it a 'official demonstration', and perhaps even there, because there would be at least 4 times as many police as skins, and they'd be apprehended at the first sign of trouble.
Nowadays, it's just an unwise idea to go to any random pub at night time / drunk people time, and proclaim jewishness.
Neo-nazi demonstrations aren't limited to half a handful of people anymore either, and police seem to enjoy arresting counter-protestors more than skins too.
And that's ... really horrible. That shouldn't be happening. Not after WW2.
Don't get me wrong. I don't look jewish (blonde, blue-gray-green eyes, no noteworthy jewish nose or ears), nor am I religious, nor close to any jewish cultural traditions. I'm just as plain Dutch as can be. I eat pig and my dick is unscathed. I've never been to Israel, and I've only been in a synagogue once in my life, on architectural sightseeing holiday with friends.
But apparently just because my ancestors (of the maternal line) told Louis Napoleon somewhere around 1800 that they were of jewish decent (Louis Napoleon instated the civil registry in the Netherlands between 1796 an 1811, and it included mandatory registration of religion), there are people that want me dead, if they find out.
And some people say 'well, then just don't say you're jewish'. But that I can't. I was raised with the conviction that after what happened in WW2, no jew (or any other ethnicity for that matter) should ever have to be afraid anymore of revealing their ethnicity, and if that is endangered, it is every man and woman's civil duty to stand up against that, and I still believe that. If you were to ever catch me punching a nazi, don't be surprised if I yell 'for King and Country' when I do so.
There was a period in my country, roughly between 1955 and around 1990 (after WW2 it took a while for the dutch government to acknowledge the holocaust's full extent in the Netherlands) were people actually realized what happened in WW2, and if you were a nazi or an antisemite, general public opinion considered you even worse than a serial child rapist. That disgust has eroded to a worrisome extent.
You can say punching them won't help, but the aftermath of WW2 sure punched them into the deepest nooks and crannies of their dark gutters for a good while.
Perhaps they just needs some remedial punching once every generation or two.
