First off, I know you're shitposting
Second off, to anyone new here -since inevitably, there must be- avoid doxing yourself by giving away info or pictures of/about yourself, lest you wish to get attacked by ironic fascists such as Anti-fa, who will attack you for acting in the favor of your race.
Third off, Sup Forums is not a nice place in the sense that you will not be... protected from what people have to say, ask or think.
If someone has a belief that you don't understand, then the most you could probably do is ask 'why?' More often than not, they will give you a rational response, and more often than not, it will be rational.
Even further often than not would be that such responses will be provided with sources to back themselves up, videos, memes and other such things.
If you don't like what people have to say not because it's real or not, but rather because you simply don't like it, then this place is not for you.
This is a center of the culture of the internet, and thus indirectly, the media that surrounds it.
If you wish to, you could change the world here simply by taking part in things. Enjoy the memes. cry at the horrors of reality, and gore that people will try to gross you out with.
If there ever was a single place in the world that could give you information on every country directly from the people that inhabit them, I would say this is that place.
But in the mean time, this is where the fun starts.
