Your confidence in this statement is beyond me. We've been there, Germany 2015, Syria crisis.
There was no lack of media representation of the conflict, the victms, etc. Of course the whole "russia vs the world" thing makes the Ukraine-invasion a different ballgame, but no way in hell would you see job boards for Syrians all across Europe if only the media paid enough attention. The media sold and told the story over and over, to anyone that was willing to listen. People just aren't as open to completely foreign cultures and to Islam as they are to Eastern Europe - and frankly, I can't take a claim that diverges from this very basic groundline too serious. Talk to actual people in Europe and they will confirm what I'm saying here.
Everyone knows someone from Eastern Europe, we know their culture, they are - like the gp said - our neighbours. Syrians are not. I've met wonderful people amongst the syrian refugees, don't get me wrong. But to claim that there is no difference in sympathy whatsoever is simply ignorant to reality, and I think your audience here deserves better than that.
The neighbor analogy summs it up perfectly. Don't dismiss it. Learn to understand it.
If there is any finger-pointing to be done then it's at the mainstream media not at how individuals or groups are trying to help human beings in need.
