If the subject comes up, I mention that fell for the cult but I am so glad to be out of it now.
One of the signs of a cult is the members are taught to have an "US against them" attitude.
By really believing this, they become social outcasts. The JW refusal to participate in the least offensive activites like Thanksgiving, extra curricular school activities, etc. reinforces this view in their minds. This is an unhealthy way of looking at other people because there are good and bad people in their own congregation, and there are good and bad people in the world. Believing that everyone who isn't a JW "bad or condemned and under Satanic influece" is unhealthy, not to mention a ridiculous distortion of reality.
