RMS is anal about meanings of terms and their use. That's not working well in the current climate where words carry perceived intent. I find myself agreeing with RMS with most of the terminology and it's use in this case.
On the other hand other discussions reveal that RMS has very bad understanding of developmental psychology, sexuality etc. and tries to to figure it out using reasoning which does not work when his model is broken.
The lesson:
If you are figurehead of some big cause, never talk aloud publicly about controversial subjects outside your field. Being a good figurehead means presenting a role to the public. All the stupid and loose talk paints the whole cause.
