"Blasphemy" is not a synonym for "something I don't like". It has a specific meaning, speaking with profound disrespect of something sacred. How does saying that the Pope is Christ's deputy on earth constitute speaking with profound disrespect of something sacred?
By the way, plenty of Protestant pastors claim to receive "messages from the Lord," which is more than any Pope claims to do. Isn't that "blasphemy," too, according to your definition?
