His pedantic personality is unbearable to me.

He held a talk at my university recently. During the QA, every time a student asked RMS a question, he would spend 2 minutes correcting the formulation of the question, and then dismissing the actual question with a snarky remark.

For instance, one student asked something about RMS being the "CEO" of FSF, followed by snarky remarks by RMS that "FSF is not a company and that he is actually the president". (I might remember wrong, but it was something along those lines)

I understand and respect him and his beliefs, but his personality just annoys me.

RMS might appear a bit difficult at times, but I don't think that was a good example. Other left-leaning founders of public benefit organizations might be mildly insulted by being called CEO as well.
