The guy stating that Warsaw has a huge LGBT movement can mean a couple of things in my book:
He probably means political/rights campaigning, something that always increases when there is perceived legal inequality.
How big are the protests against the abortionslaws in Poland?
Huge.
Remember that Warsaw is the most affluent (and the only metropolitan) city in Poland. The UK has London and also Manchester, Edinburgh, Glasgow, Birmingham. France has Paris and also Marseilles, Bordeaux, Lille. Germany has Berlin, and also Frankfurt, Hamburg, Munich. Poland has Warsaw and it has the provinces.Therefore, its residents are on average far better educated and more affluent that the population as a whole and this is not replicated elsewhere in Poland. For this reason, most campaigning organisations and those who support them are based here, and the views you are likely to encounter in Warsaw are more likely to be those of intelligent and well-educated people.
