Hi Den,
May I say just a few words? Please, please, please stop. Wars of words don't accomplish anything good.
1. Gotta treat everyone with respect. Atheist, Agnostic, or Christian, just the same..... Yeahh, being assertive may feel great, but being submissive fosters a friendly conversation. So, choose.
2. And please remember that.. if you're a believer, you're not a soloist...you represent the church, so please don't defame it.
Thanks.
