It was not only Alexander's thoughts that were very different from everyone else's but there was also the fact his worldview about the status of nobility and bloodline was also vastly incompatible.
While the people of this time saw the status of being a noble as a god-given honor and believed in the superiority of bloodlines, Alexander was half a technocrat, believing that the more knowledgeable a person was, the more respect and recognition he deserved.
He put science and reason on a pedestal, not dogma and ignorance.
Thus Alexander simply saw his noble title as a tool to control the populace and thus improve his life and those close to him.
So naturally, he would not fight over such a trivial thing as a nobleman's honor.
And the only time Alexander would try to defend himself from being mocked would be if he was attacked publicly, as his prestige among the people was paramount.
