I would consider in this forum marking a post with a negative rating rather than a counter argument to be closer to that first sentence. A counter argument says here is what I think. Now change my mind. Which is exactly what I do.
Immediately calling something fake news without offering proof that it is fake news is closer to that as well.
Now when it comes to being a
dogmatist, partisan, sectarian, prejudiced person; racist, racialist, sexist, homophobe, chauvinist, jingoist, anti-Semite
You will have to show me where I have been any of that.
Partisan does not count because of nature of the site itself.
