When travelling from Poland to London by coach in the 1990s, all the Czech nationals at Dover were whisked through with no problem, but all the Poles were given the third degree, and always, without fail, at least one or two from each coach were deported. There's much more I witnessed on a number of occasions at Dover, but I'd be trolling here.
I think you just answered the question there.
But so where Slovaks, Ukrainians and Hungarians, and yet who has ever heard of Hungarian, Ukrainian or Slovak jokes?
It's a question of numbers.
Obama outdid himself trying to curry favour with the 6-million-strong Jewish electorate but never bothered to address a single PolAm group during his campaign although our Polonia number 9-10 million.
Here, it's not just a question of numbers. The average Jewish American is a bit more influential than the average Polish American. Not to mention, that geopolitically, Israel is much more important to the US, and the politicians than Poland. Not an opinion, just calling it like it is. Or maybe it's a question of organization... Also the Jewish vote is fairly single issue, whereas Poland doesn't have issues with its sovereignty :)
What rights? Well, for one taxpayer-funded Polish studies in schools similar to holocaust studies, Afro-American curricula, Hispanic studies and the like.
If no one wants to study it, and no one finances it, why should a university offer it? You mentioned it earlier, be assertive, that's what the US is all about. Start a program at your local college. The US, despite where it's headed, isn't a fully communist nanny state yet. You can't sit back and wait for things to happen. Take that money that you wanted to invest, and start a program.
