Greetings, Savannah! I notice you haven't been active at Atheist Nexus for a year. <sigh> Sometimes it can seem a bit fragmented, with different groups for every interest. Please consider a group for socializing, where we talk about whatever's on our minds, Hang With Friends. :D You might feel more at home.
Hi Savannah and welcome to this great meeting place
where religion is recognised for the superstition and people-control fraud that it is and for its inexcusable 2000 years of oppressing women
--- and that God and gods are merely fictions inside human heads.
Besides your father and sister who largely understand you, you now have vast numbers of good friends here.
There's not enough room in the private message thingy, but what I was trying to point out is that if your family is full of religious nutters, then there's always a chance that some of them try to 'check up on' any members of the family they think might be 'straying from the pack'.. unless you're comfortable with the rest of them finding out about you, it's probably a good idea to just use your first name (or a pseudonym) to avoid detection. Only 40 minutes after you created this page, it became the first google result for "Savannah Keller" o.o I tested it as soon as I read the bit about your family, because, well.. you hear stories about that sort of thing :/
Of course, you may not care, but you do kinda have to live with those people, so yeah...
Either way, good luck when/if you do come out as a -gasp- 'heathen' :)
