The reason why people dismiss a lot of criticism against Soros is because a lot of the criticism is not based in reality, period. I am more than happy to criticize rich billionaires but the meme around Soros is clearly based around the anti-Semitic idea of a Jewish cabal running everything behind the scene rather than any sort of issue with wealth.
Vladmir Putin also has plenty of innuendos about killing people. However he actually does have them and has taken pains to make it clear it was him doing stuff like using rare nerve agents instead of any far cheaper method of assassination - just common cyanide in a large enough dose kills just as well as polonium, better in fact but it causes too quick and clean a death for terror purposes.
Why are people accusing him of unfounded stuff, as you say they are doing. What is their reason to make up or spread unfounded accusations that rile these other folks up that you mention, why are they doing that, do you think?
For an example of the last going on about say Obama's college essays don't really mean anything in comparison to what he has actually done - it looks to be downright racism in holding him to a different standard bring and not care about say Rick Perry getting D in a course called "Meats".
You could reasonably call him out on say his foreign policy continuing bad practices or what he signed. Calling him an athiest Muslim who prays in a mosque communist born in Kenya would just be bigotted literal nonsense.
