You seem to be talking in global / political terms, where I'm more concerned about the internet as a subtle, but equally powerful way of changing how people think and behave.
I would hope, especially in the west, that government isn't an issue, and that no one group is going to have the power to impose their dogma onto anyone.
However, just because a group can't politically force dogma onto others, doesn't stop them from being a threat to spirituality, religion and faith. Especially with the help of the internet, where anti-theistic dogma is represented and spread as if complete fact, faster than any religion has ever had a chance to spread.
This is why I'm concerned. There's a clear anti-theistic movement to belittle and degrade believers, while spreading emotionally compelling half truths. This pseudo-science and flawed logic, disguised as "rational thinking", seems to be having a great effect on a very large number of people.
