Very true. You are correct. However many will be able to see through the illusion and have discernment. In my humble opinion, many of the people who visit FR are aware and have such discernment. They look for facts and do not get caught up in the emotional whirlwind. But even more important, they trust that knot in their stomach to warn them when something is not right! This is the same knot that keeps many soldiers alive on the battlefield. It only comes through an inner strength, peace and faith.
The tribulation is described in Revelation chapters 6 through 19.
