Intelligence challenged people and free speech

In the post below I took the time out to link to the GSS, as well as posting my exact queries. As payment for this consideration the first comment was absolute drivel. I understand people have political opinions, but I'm not too interested in your opinions. You may be interested in your opinions, but I'd rather have more data. Most people don't know enough for me to have interest in their opinions (most != all, many readers do have opinions in their specialties which I seek out).
