Are you an open or closet agnostic/atheist, and why?
I'm not totally open in the sense that I don't generally announce it. When asked I'm not hesitant to state my views.
I get to "cheat" a little bit I suppose. When around fundamentalist Christians I can honestly say that I'm "Jewish/agnostic like my father before me and his father before him.
The "Jewish" bit give me a little leeway as most fundamentalists tend to respect Jews.
That last bit may well be changing what with Trump's friends giving the Nazi salute while chanting anti-Jewish slogans.
I'm an open one: I really like confrontation (a polite one)
especially 'cause I'm trying to live leading by example (kindness, generosity, etc support by knowledge) showing to religious people that we don't need a God to act in a good way;
usually, I like to show them that I know much more on their religious than them, quoting the bible against them (quite easy to do it)
I suggest to watch all the Richard Dawkins arguments on youtube that literally trained me to deal with that (now I'm able to argue with my evangelic sister that, opposite to Catholic, they know how to answer you properly making the discussion quite harder...
As a brown Army veteran, I am less hated for being an atheist than a Muslim. If someone asks my religion I will happily tell them I'm an atheist. In the more common way I get asked, I refuse to deny being Muslim. I ask "does it matter?" and "why?" and wait for serious answers. But generally, I am very open about it.
I am an open atheist because it is important for people to know that atheists can be good people, and I try to be an example of that. If we are more open about our views, more people will feel like they can come out as well without being judged.
I am open about my atheism. I am surrounded by a family quite into religion and live in the UK. I feel for my brothers and sisters in more theistic communities, I.e middle East and the US where you would be forced into staying quiet...literally in some cases to save your life or your job!
I seek to fight intolerance in all its forms. This is fair, right and honourable.
I don't hide it, but I don't push it onto my religious acquaintances and friends either. Some of my best friends are deeply religious, they know my belief/opinions, but we love each other like brothers and would do almost anything for our group of friends. So, y'all tell me, does that mean I'm open or closeted?
I have been an open and sometimes vociferous atheist/evidentialist/rationalist for a mite over 60 years. It has been a box of different rocks most of the time, but I have thick skin and a good understanding of human behavior and how the world works, so it has seldom been much of a sticking point.
As for the 'why' of it, I find it much easier to live an honest life and I don't like having to make shit up -- except when I'm writing a book, then I love making shit up.
I came out of the non-believer closet in January. I had to wait for my daughters to leave for college to do so. Boy oh boy did it stir up some noise in my small community in south Arkansas. 99% of people here would say they don't know an atheist/agnostic person. The few, very few that are here must stay in the closet or risk their careers and family.
I currently live in the bible belt, which is unlike any other place I've lived. It is extremely discriminating. I've had countless people be downright rude about it. Even tried joining a local volunteer group in my area (they donate blood, work at the food bank, give to Children's Miracle Network). How stunned I was when the organizer inquired about my membership in an Atheist group (my profile didn't hide it and I didn't try to). She said if I wasn't going to volunteer at all the meetups, including religious, then I couldn't join.
This behavior is why I leave it out of my professional life. That's where it matters. I can't have it hurting my livelihood.
With friends and family, I'm open.
I've been very open for about 40 years. If I am ask or questioned about my beliefs. I live in the bible belt and my beliefs cause many to question my value. I found very little problems in the educational surroundings I found in my life as a teacher.
