@aral You seem to be confusing politics with ethics, Aral. 99% of social media users seem to make the same mistake.
Politics is riven with corruption and avoiding having anything to do with it certainly doesn't equate to being uninterested in righting injustice. I'd argue that politics actually gets in the way of principles, because once somebody has identified with a political party the next step is to toe the line irrespective of one's actual beliefs.
In other words, you're wrong, mate.
