The “loose definition” redtea came up with is bonkers.
Additionally, as you say, words have meanings. When people criticise NATO it is as a stand-in for the imperialist world order. It includes the IMF, World Bank, the WTO, the ‘international’ courts and rules, and all their elements and capitalist lackeys. You’re making a semantic argument, which misses the crucial point: that NATO and its member states are concerned only with the wealth and power of their bourgeoisie, regardless of Russia.
I’m not trying to hide the fact that I have an agenda, that we can’t have world peace until there are no more imperialists, which includes and is often, in ordinary language, represented by NATO. If you interpret that as support for Russia, there’s not much left for us to discuss.
