I learned to read at four via sight reading and am a published author, so perhaps you want to reconsider your claim that sight reading breeds illiteracy.
If you learned to read at age four, you did not learn to read through any sight reading program used in public schools since you were not in school yet.
Since memory from that early age is quite spotty, how do you know how you were taught to read?

I made no such claim, nor did I use the word "illiteracy" at all.
