My point is only that it's *people* who teach -- not an idea.
Secularism is an idea only. It cannnot teach, because it doen't have to ability to do anything on it's own. It's inanimate.
However, I do believe that secularists -- the people who agree with the ideas inherent in secularism -- can be just as intolerant as any other person. They too can assume that they alone have the "truth."
Just my wandering thoughts here. Ideas don't teach -- people do.
Shalom!
