The issue is not RMS's beliefs as such. It's how he chooses to communicate them.
There's no doubt that there are many people in positions of power with beliefs that many would find reprehensible. But most of them have the sense not to make those beliefs public.
Of course one can make the argument that RMS can't help it, it's just his personality/ disability (as Bruce Perens recently argued), but that infantilizes RMS and implies he's simply incapable of learning from his mistakes.
But he is capable of such learning, as his recent presumably coerced "apology" shows. He needs more of that to develop into a mature adult person.
