A film review - Pride

United Kingdom, 1984. Europe is struck by the economic crisis. Unemployment rises(/Unemployment rates rise) rapidly and the government has no money to do something about it(/lacks the resources to do anything about it). In that  (+ the midst of)  those conditions, Margaret Tether has decided to close tens of coal mines throughout the country. Miners announced a strike.

In that time period, a London group of LGBT activists decided to support the striking miners. They gathered a significant amount of money to transfer them to the miners' families. However, they did not expect that they would face with (/would be faced with) hostility and unwillingness to accept(/resistance towards accepting) their help. It took time for these two, seemingly infinitely distant minorities, to grasp their proximity.

The film director tells a story about real historical events, about real people. In my opinion, he wanted to convey the idea that it doesn't matter what your sexual orientation or religion preference(/religion) is. There are things uniting all of us in the(/this) world. We call them *happiness and the desire for well-being. (you could also write -- "There are things uniting all of us in this world: happiness and the desire for well-being" or "There are things uniting all of us in this world, namely happiness and the desire for well-being" )

*"We call them" doesn't work that well in this context. I think the closest, good uses of "we call them" might be "Everyone feels a sense of unity with mankind and the universe - we call this god, we call this faith, we call this energy, whatever we call it, it is a transcendent aspect of mankind"
