Depends what you mean by crazy. I would argue that believing the events of Dracula actually happened is equally as crazy as believing that the events of Twilight happened, notwithstanding the fact that the former is a much more coherent and generally better story. And for what it counts I would tend to agree that the cosmology of Islam, for example, is much more pleasing in an aesthetic sense than that of Scientology.
The difference between Twilight and Dracula is the difference between Christianity and Islam. The difference between Dracula and a version of Twilight where Edward was secretly a robot piloted by tiny Martians who survived the great galactic war and taint your soul which gives you all your mental problems, that is the difference between any other religion and Scientology.
Also, falsifying records pertaining to themselves, harassing or litigating against people who criticize them, abusing/torturing/killing members who try to leave, and using government organs to spread their influence are things that all the major religions have already done (it's how they got major).
Somewhat yes, but I'd have to say mostly no. I don't know of any case of falsifying government records on the part of other religions, which was a treasonous act committed by the Church of Scientology alone so far as I know. Litigating in modern times if you mean that, but it's not the go for broke, destroy your life, harass you into oblivion brand as with Scientology. Spreading via government I didn't mention, but I will say that when that was done, it was the government spreading the religion such as with Spanish missionaries or what have you.
The sins that religions have committed in that list are killing and torturing, but to get to when such were done in the form of Scientology, you have to go back to Medieval times and times before that. During those times, the reasons for that was one of Theocracy where religion was the government or was part of the government, and as such those things were matters of sedition in the eyes of that. It wasn't just a group doing that.
If it was not theocracy, it was then simply a case whereby the persecution was coming from a ruling segment of the society that was part of a religion persecuting a differing religion.
Beyond that, it was simply a case of sporadic bigotries without a unity. Christianity was there, and the KKK was killing blacks from a Christian belief (a distorted one), but they were not speaking for Christianity because they were not being ordered by a Pope or anything with the whole of Christianity behind them. And even in the cases where I did mention theocracy and religion as a branch of government, that was distinct from Scientology also in the form that past a certain point in history, it's not one figure and not a unified doctrine directing that and not a well organized Church overseeing it and directing it, and it's just the bigotries of people. In Scientology, it is a leading figure and leading body organizing things in a very organized group carrying it out.
And the point stands that this is not 1000 AD, and Scientology is not some large government force or a force mixed in with government in a way where it really is part of it, such as were the religions when they did those things that they truly did. It was founded in the 20th century and this is currently the 21st century. These sins that Scientology has committed are inexcusable and absolutely criminal. The Lutherans aren't infiltrating the IRS, and the Baptists aren't starving people who are thinking about leaving the church. If they were, you could be damned sure a giant hammer would come down on them, though it'd be difficult to have that given Protestantism means a lack of unity and lack of a leading figure and organization. Scientology is Papal and well organized, and carried out those things and continues to carry out such things as an organized group.
Another distinction is that other religions have a true spiritual base of an explanation of God and an explanation of the universe, whereas Scientology was founded and continues to operate simply to get money, and to get power as well in order to support the ability to get money and spread influence. When a religion in the past were to get to a huge number and act with authority in the bad ways mentioned, it was with an internal belief that it was acting for it's God against wicked forces, whereas Scientology does so because it's power is perceived to be threatened, and that power is there in order to gain money and to support the higher ups and elites within the organization. Where such happened in organized religions, that was at points where churches had become corrupt, whereas with Scientology that was the full intention from the get go and is not corruption but is rather how the organization was intended to operate.
