How many opinions of Justice Thomas have you read?
I have read many of the court decisions handed down under the current court and from over the years. You cannot get through a Constitutional Law class without doing so.
Thomas rarely writes the majority or dissenting opinion, and it would seem that this is because he is not intellectually up to the task. I cannot think of any other reason. I am not lying when I tell you that when he does take the time to write, the opinions are usually very short and basically concur with Scalia and he throws in a point or so he wants to make. With all due respect, he is an idiot.
Puffy makes a wonderful observation about Scalia - sometimes he writes brilliantly, but even extravagantly dressed crap is, well, crap.
Read his dissent in the Texas sodomy case and count the fallacies.
