Yes, and Jesus told us why:
But he that received the seed into stony places, the same is he that heareth the word, and anon with joy receiveth it; Yet hath he not root in himself, but dureth for a while: for when tribulation or persecution ariseth because of the word, by and by he is offended.
-Matthew 13:20-21
They are offended because they hate the idea of persecution or tribulation because of the Word of God. They want the happy-go-lucky, funtime, feel-good message only, and the false prophecy of pre-trib gives them that warm feeling inside where they don't think they'll have to suffer anything except the woes of how to have more faith when their dishwasher breaks down.
Remember the word that I said unto you, The servant is not greater than his lord. If they have persecuted me, they will also persecute you; if they have kept my saying, they will keep yours also.
-John 15:20
