Jedi of the Matrix
No, No, No, and maybe.
1) The Fremen are men (and women) that traveled the galaxy from planet to planet searching for their own home (and actually, it was forced by slave traders) the tusken raiders are just (well, i am not exactly sure what the species is) that lives in the desert of a planet that has no marketable resources, and is only habitated (is that a word? not exactly sure, but too tired right now to check) because it is close to trading lines.
2) Baron Harkonnen, which if you had read the House series,you would know, is only fat because he raped a Bene gesserit and she gave him a venereal disease on purpose, as a reward for his "conquest". Jabba is fat because he finds it to be handsome, and because of his genetics.
3) No, they are similar, but there are differences. such as, the bene gesserit are only female, jedi can be male and female; bene gesserit utilize their minds in such a way that anyone can be trained, whereas jedi must be born jedi. etc.
4) yes, Arrakis and Tatooine are both desert planets, however, there are differences there too. namely, Arrakeen sandworms can travel the sand, and live off the spice (and that which is mining the spice) and the Tatooine sand worm is immobile and eats whatever falls in its gullet. Tatooine is habitable (if it can be called that) all over the planet, whereas one can only live on Arrakis is only habitable on the sand in the northern and southern reaches, where the sand worms can't travel.
in other words, i did think about it, and i disagree. on first glance, yes, there are similarities, but on further examination, obvious differences arise.
