I am at a lose to respond line per line but let me assure you, if you have committed the unpardonable sin you will never care that it is unforgivable. It's a condition known as perdition, the devil is in this condition and so is everyone who has sold out to sin. When Jesus was talking to his enemies they said he cast out demons by the power of Satan, in effect. They said he cast out demons through the power of Satan. Jesus used a little simple logic, if Satan casts out Satan then his kingdom is finished. The only way to be saved is to be cleansed by the Holy Spirit of promise, there is no other way. When they called the Holy Spirit unclean it revealed an irreparably flaw in the seat of their moral conscience. I think they knew that they were seeing God work in peoples lives and they were simply angry because God had intruded, all sin is at enmity with God.
It's like when Jesus called them hypocrites, Jesus was using a term that meant literally, 'one who wears a mask', it was the idea of Grecian theater. The actors would change masks as a part of the performance, Jesus used this image to indicate a religious phony that fooled neither the audience or the actor. They knew they were phony, Jesus knew they were phony and he was telling them there was no escape from that. Jesus talking about Judas said one of you is a devil, not you will become one, but you already are. There are questions whether Judas could have repented but I'm convinced there is no way he ever intended any such thing.
No child of perdition has remorse for their blasphemy so if someone utters slanderous things, even about the Holy Spirit, it's not necessarily the same unforgivable sin Jesus is describing. I really don't know, only God can tell the intent, but my guess is if you say something you don't really mean or understand it's simply not the same thing.
Grace and peace,
Mark
