I understand the Ukrainian invasion is sickening/a travesty but I struggle to square what appears to be an underlying hypocrisy.
While there's a lot to criticize about US foreign policy, invading a western nation with a democratically elected government isn't on the list. You really can't sympathize with Saddam Hussein or the Taliban. I wouldn't (and didn't) stop paying taxes over it.
If the US government invaded Mexico or Canada, I might.
In the U.S. it is even coded into the Declaration of Independence.
The world is organized by a small group of countries and power blocks that are in charge, whilst the other 90% has no meaningful economical or military relevance. This in no way makes it "more OK" to do harm, I'm just saying the selector is relevance, not race.
Of course, Putin should be condemned, but it is interesting how nobody held the US to a similar standard.
Protesting the war is one of them. Leaving is another.
Being complicit and dying are not the only two options.
I fail to see how protesting the war is a "way to not pay Russian taxes". Unless you specifically mean refusing to pay taxes to protest the war, which would go about as well in Russia as it would in US. Well, except that, once you get arrested, the cops are likely to "entertain" themselves by e.g. putting a gas mask on you and squeezing the hose. Or shoving a bottle into your anus. Or just beating you with rubber batons until you pass out.
Do stores refund your VAT if you have a protest sign or something?
Russia has been an authoritarian country since 2011 at the very least - and arguably longer, just of a softer variety prior to that - when the regime crushed the largest protest in Putin's times (https://en.wikipedia.org/wiki/2011%E2%80%932013_Russian_prot...). By now, it has a special branch of internal armed forces - National Guard / Rosgvardia - which is used primarily against protesters.
So yes, there's a big difference in practice.
It's dehumanizing and depoliticizing and should be changed once Putin is out of power.
