Venezuelans who come to the US tend to be wealthier, in order to be able to get here, and have enough issues with their country in order to leave, issues that they will usually blame on the leadership.
None of this is to say Maduro has majority support, he doesn’t by most accounts, or that they don’t represent a sizable chunk of Venezuelans who don’t like Maduro, but that his support isn’t as non-existent over there as it is here.
It’d be like if Trump took over the US and you only got your views on what Americans think from expat communities in Canada. They would probably cheer his death, even if it was by a foreign empire, but that wouldn’t be representative of average Americans who probably wouldn’t like the foreign intervention, even if they don’t like Trump.
This is true for almost every expat/immigrant community I’ve interacted with, including my own. It’s pretty obvious in voting pattern differences between the expat community and the native country. The far right gets 30-40% among Bulgarians in Canada compared to 10-20% back home. The left gets 1-2% here compared to 7-10% back home.
The Dutch immigrant groups I’ve been part of have also been scarily right wing. I don’t bother anymore.
The biggest far right group in Germany are the Turkish grey wolves.
