I second what Sparky said, and I'm going to add more info.
eaglecage, for someone who claims to be interested in Scientology, your questions and remarks are consistently shallow and uninformed.
Wikipedia didn't ban Scientology because it's an evil, criminal enterprise. If that were the reasoning, Wikipedia would also ban entries on the Mafia and North Korea. Those entries remain.
Wikipedia banned known Scientology IPs because Scn, unsurprisingly, has repeatedly broken Wikipedia's rules against self-serving edits. Wikipedia warned them many times, and, again unsurprisingly, Scn ignored the warnings.

According to evidence turned up by admins in this long-running Wikiland court case, multiple editors have been "openly editing [Scientology-related articles] from Church of Scientology equipment and apparently coordinating their activities." Leaning on the famed WikiScanner, countless news stories have discussed the editing of Scientology articles from Scientology IPs, and some site admins are concerned this is "damaging Wikipedia's reputation for neutrality."
Wikipedia is not a democracy and has never allowed free speech. It is an encyclopedia, and, ideally, allows only informed, neutral speech. Its job is to offer truthful, unbiased information, not steaming heaps of Scienoshit.
Banning Scn is in the best interests of Wikipedia's readers.
