Speak English at any of these events and you will get your face smashed in. These people are nationalists they will want nothing to do with you
That's not true at all. ONR/NOP welcome anyone who believes in nation's sovereignty and for native citizens to determine the country's destiny. Their website is in English and Polish and they have many members in the UK and US - especially in Chicago.
You do not necessarily need to accept third position ideology to be welcomed - wanting to preserve a Christian European society is more than enough. And yes, ONR/NOP do work side by side and support other nationalist groups like Pegida, UKIP, Golden Dawn, Forza, Identitaire, Jobbik, AfD, etc. They are part of the Alliance for Peace and Freedom and coordinate with the aforementioned groups. This alliance has a few MEPs. Most of the nationalists (although yes there are exceptions) are promoting more cooperation and the more senior members and leaders of these groups with other nationalist groups. The ideology is that we're all Christian Europeans and there is a FAR larger threat from the Muslim invasion and EU's promotion of gay propoganda, destruction of the traditional family unit, hatred of Christianity, social conservatism and traditionalism, etc. Yes, ONR/NOP did complain at one point about the Ukranians - this is nothing new or specific to them. According to CBOS, half of Poles support Ukranian migrants, half do not. Naturally it's the same in these circles. Nonetheless, this is the nationalism of the 30's with France v Germany, Spanish liberals v falangists/conservatives, etc. Nationalists groups from Spain to Slovakia, France to Greece are cooperating, hanging out together, exchanging ideas, having fun outdoors, drinking beers, whatever. They see themselves as kindred European brothers and sisters - not enemies. But yes, there's obviously differences - many nationalists support Putin's policies but Polish and Ukranian nationalists generally don't. Yet Russian nationalists frequently work out and train with their Polish counterparts and are friends. Each group has respect for each other's nation - the purpose is to fight against the EU dictates and the migrants - not to fight against people who all desire similar things.
A perfect example of this is the Ukrainian flags intermixed with Polish flags on the independence day marches. You'll even see a few Poles, Croats, even a few French and Brits with their flags in Right Sector, Azov, etc. events. 60k people in just Warsaw alone this year. Some marches had even 80k, 100k in Warsaw alone. ONR/NOP support for Golden Dawn - nop.org.pl/2018/02/08/ateny-glos-narodowej-rewolucji
ONR/NOP have many summer camps, hiking outings, social events, etc especially in the summer over the weekends. There's a surprising amount of beautiful young Polish girls at these events too. There are thousands of RN/ONR/NOP members all over Europe and offices in every major Polish city. They also organize motocross rallies, runs all over europe, etc. There's a lot of bikers in these patriotic groups as well. A lot of RR's and other 1%ers are members of such groups as well.
These groups tend not to field candidates and run serious campaigns - it's more just to get their name out. They primarily support Kukiz, a few PiS, but none PO. Nonetheless, RN has been able to gain Sejm seats.
