Sure, though it would be peppered with me asking for clarification of terms and other good stuff.

Again, my main point is not with ET.

Getting away from ET...

Take as an example the James Watson controversy. Most of the people that attacked the man didn't even read his words. Is is possible to have a rational discussion on the topic? My argument is that although there is formal freedom of expression on the subject, you cannot informally discuss it as you might get into big trouble.

The same line of reasoning can be applied to, say, freedom of expression in the work sphere: in theory you can give feedback and complain. But in practice these freedoms are very limited. With time, people start finding these restrictions normal, and that is a disaster.
