I read the article. Then I wondered, since I didn't seem to fit into any of the categories it defined: why the need for such categorisation? Then I re-read and found this:
If prejudice continues to exist towards atheists in general, one source may stem from the perceived negative experiences by religious people interacting with a very small sub-segment of the overall population of non-believers, mainly the Anti-Theists. In other words, our research showed over 85% of the non-believers sampled to be more or less your “average Joe” when it came to being “angry, argumentative and dogmatic”, they fall right in line with current societal norms, nothing strange here - sorry non-believers, you’re pretty normal when it comes to being psychologically well-adjusted.
I imagine that some members of GN think I'm an activist atheist. What they don't know is that gransnet is the only place I talk about atheism. And that's because the gransnet forums are talk forums, for talking about stuff that interests you, including stuff, like atheism, that you don't get to talk about anywhere else except in your own head.
Besides, theism/atheism is a more intellectually stimulating subject than many. That's part of its appeal. It's a good subject for debate – plenty to chew over.
