only No 2 and 3 look like typical Polish peasants.
I dunno.... there's a peasant market in town I go to sometimes and 5 and 6 look more like customers than sellers... I think 1 and 4 could be either....
Polish (and in general European) farmers have a lot to be angry about especially daft green policy that wants to cut production (who needs food?) but I don't think any of them are especially motivated by ideology, more by practical day to day paying-the-bills problems.
And now a bad combination of PiS's failure to keep Ukrainian wheat off the market, stupid EU anti-agriculture policies and (probably foreign) moneyed interests wanting to turn Ukraine into a massive agricultural collective (a la Almeria, Spain) is driving current protests and not any kind of pro-russia ideas....
