What do you think about Immortal Technique and underground rap?

I shall express my opinion as it's a fact that really concerns me. I think that underground rappers like Immortal Technique exaggerate and create a huge number of presumptions about the Government, and not only. They fuss too much about mainstream music too, which is a thing that I also found childish. They use neological (words inflicted in the scientific spectrum, philosophy) explanations in their phrases just to look smarter than they are. I am not saying they are dumb, but I still think they have a ghetto mentality and the fact that they "spit on the mic" trying to change the population will not have a major impact on the mentality of his fans. I think that underground rappers are also using dictionaries to create his lyrics, which is indubitable. I dislike the fact that he thinks he is a philosopher and he subliminally thinks he is a genius, because I think a lot of these mainstream artists could also talk bullcrap (sorry for the bad expression) about politics and express their own opinions, everybody has got personal opinions. And I think, that by using a dictionarry, everybody with a moderate IQ could sound exquisite and elevated just like these underground rappers try to sound. What is your opinion?
