I will certainly address it.
The fact there is a thread saying atheists are discriminated against is silly to begin with. Every faction of any group of humans is discriminated.
The fact he presumed believers to be downplaying anything only adds injury to insult. It insults me as I include myself he the group he was refering to.
Is that good enough for you?
Wow. Im sorry, and I may be way off, but I am certainly getting some strong emotional cues from your post. When you start saying things like things are "a joke", and that you feel a poster is "adding insult to injury" directed to you, it seems clear to me that you are, for lack of a better word, agitated....or at least seem to be taking it personal. I will go back and re-read the thread just to make sure I am not off base.
Also, if you feel that a discussion about Atheist discrimination is "silly" to begin with, then perhaps you should just not participate. To deny that some people are not treated differently for their religious beliefs (or lack of) is what is silly. I am the recipient of this type of treatment all the time, and I am only agnostic.
It really isnt your place to determine the validity or degree to which it takes place, especially when it is dealing with another persons personal experiences.
