As for Christianity, if Torba is faking it, as you seem to imply, he will give an account. Like I said, I rarely talk to him. Ironically the last time I talked to him was when I told him I was not a fan of the Jesuits. As you are likely aware, the Nazis took plenty of direction from Rome. It is all well documented, even on
Wikipedia.
The point though is not to throw the baby out with the bathwater. There are sites that allow free speech, and those sites have misinfo and disinfo but they also drop gems that is often hard to find elsewhere. Also, I think Dissenter will be bigger than Gab. The fact is that Gab has too much baggage at this point.
As for the user count, I am sure your numbers are low. Gab users extensively rely on VPNs, including one from Epik, so there is no way the user counts will be visible through any conventional tracking metrics. Gab users are some of the stealthiest users on the Internet.
