The American hating is not as described, not everyone critical of US foreign policy is wrong (the Americans certainly aren't perfect). But there are quite a few who do have that 'knee-jerk' reaction to anything the US does and this makes no sense either.

Interventionism may be necessary if all other means have been exhausted or are of no avail. The US has intervened for less than altruistic reasons before, but they have to call these something else (it wouldn't be diplomatic to explicitly state they intervened to "encircle" an enemy or "secure" some strategic point). The targetting of some human rights violators and not others may be a consequence of inability to tackle them all at once and a need to prioritize. 'Support' for tyrannies is something more prevalent in the past than of late and even so is moderated by other sensible considerations like strategic location enemity with one's enemies, natural resources, local and regional stability. Pursuit of 'national interest' is what foreign policy is supposed to do, not some obsessive American aberration (I'm sure even Euros would be outraged if their foreign ministries were shown to pursue a foreign policy contrary to their 'national interest').
