I don't get being ashamed of a trait like nationality for any reason, let alone because of government decisions. Be disappointed, angry, frustrated, appalled at those choices, sure, but ashamed of a trait of mine because of something out on my control? I don't see the benefit.
People are not the governments of where they have nationality or are living. British people and residents of Britain are not the British government, Russian people and residents of Russia are not the Russian government, and so on.
There will always be a broad range of what people are doing and worldviews within those groups. There are many in both groups doing amazing things, we can't be boiled down to our nationalities or the governments connected to those nationalities and residencies.
The systems of movement have become extremely complex in the last century as governments have taken more control while people have wanted particular border securities that comes with that control. The oldest refugee camps are over 70 years old, homes to thousands of people. It's a large mess, it's frustrating how much is political and profit barriers, but it's not something I'd say I'm ashamed of.
Really, as much as the immigration and asylum systems are largely profit and political games, I think supporting the countries that are going to be providing the bulk of the support in any case and focus on the reforms that would make movement easier as a separate issue. Those I know in Poland, there is a ton going on, but often there isn't space for supplies or the infrastructure to do so. That I think is a more immediate issue that I know some Brits who are helping with.
It's standard for refuges with brown or black skin.
Haven't heard much complaints about this previously.
There usually is a buzz of things at the start of events, but it often dies down after a few weeks to months when compassion fatigue kicks in and other issues take over. There is a bias in how long the media tends to keep attention on them, but there is usually a spike of complaints either way.
