Re refugees, this is a difficult one for the British.
This is because for a number of years now there has been a particular nasty undercurrent in British press and politics, a strong anti-European and particularly anti Eastern-European sentiment. I hate this phrase, 'Eastern European', there really isn't such a thing as it refers to people from what geographically is Central Europe and Eastern Europe. It is also offensive to me, as in, very post-Soviet aka 'the Eastern bloc'. We are individual countries, sovereign nations and democratic republics. People talk about France and Germany, not 'Western Europeans'. Talk about Poland, Czech Rep, Slovakia, Ukraine, Romania, Bulgaria and other countries equally then, as individual countries.
I'm digressing, but the point is, the above narrative has informed the politics of the UK Home Office. Consequently, the UK is not doing anywhere near enough in this refugee crisis. There soon will be 1m Ukrainians seeking refuge in Poland in less than 2 weeks. Mostly mothers with young children and people with disabilities. Let that sink in. Poland has to deal with it and is getting on, it's pretty incredible. Meanwhile the UK...not even a drop in the ocean considering the scale of it.
I'm not being bitter in response to the question how to help, but I'm angry that you as a society are not given the opportunity to welcome these people and truly help because of your politics. And frankly, not enough people and politicians speak out against it either because there have been endless buckets of mud thrown at 'Eastern Europeans' unfairly to achieve Brexit and so there is some distrust in British society, sadly. Unfortunately, the xenophobic mindset against 'Eastern Europeans' still dominates the Home Office.
I think the change of rhetoric and respecting Ukrainians, Poles etc as equals would be a good start. That's very basic but key as it makes people feel welcome and comfortable. Then the specific help depends on the individuals, if you welcome refugees. My friends and family in Poland offer their own homes, share food, offer jobs in their businesses in accordance with the refugees' qualifications. So not any job will do because you're a Ukrainian refugee. No, you're equal to us and you need help, so we'll help you out. This is the spirit. Everyone has faith that this will pass and everyone knows these people need some normality. Then when things calm down, they will want to return to rebuild their own country, to hopefully reunite with their husbands and fathers. Ukraine will always be their home.
So that's what can be done for now. But like I said, the reality is if HO policies don't change you won't see a huge influx of Ukrainians here. So the next best thing is to donate money to help this group of refugees and buy items that are required at any given time and donate through organised channels only - the Polish community in the UK is extremely well organised by now, if you reach out to them locally, you'll be guided as to how you can help.
