In such situations, the simple act of ecouraging more open inquiry is often attacked by others as "intimidating". Those who do the attacking deal with their feelings about possibly being wrong by blaming the more open individual for arousing these feelings and upsetting them.

I have difficult in catching the meaning of the underlined expressions.
The people doing the attacking realise that they might possibly be wrong, and this causes feelings that (presumably) they don't find very comfortable. They respond to ("deal with") these feelings by blaming others.
Thanks. You make the meaning very clear.
