Being offended by #3 isn't really unique. The whole anti-Israel vs. anti-Semitic thing is a good example of this difficulty. Same with people being critical of long-standing American institutions -- Americans get offended. The only time people can really make it clear in their mind whom they are criticizing is when they are criticizing a particular leader, e.g. Trump, Xi, Kim Jong Un, etc. Everything else just riles people up for no reason.
