"My foot stands on level ground; in the great assembly I will bless the LORD." - Psalm 26:12
I have a strong feeling that I would not be welcomed here, for I am not Christian and no intent to be.
This is only 1 step removed from "We prefer only $religion here." Or another way to look at it, is "We dont like $your_religion." They aren't out-right saying that, but the dog-whistles are most certainly there, biblical quotes and all.
No matter how you shake it (by preference or by refusal), it's coming mightily close to breaking federal law as cited here: https://www.eeoc.gov/laws/types/religion.cfm
I would understand if the organization was a church or religious group. But it seems to be pretty bog-standard tech shop. It, at absolute minimum, is a warning sign of potential religious discrimination. To put it bluntly, unless there's a religious component in the nature of the job, the very fact that religion is mentioned on their pages is at best off-topic, a warning sign to all, and at worst a potential sign of EEOC violations.
Some would argue that politics is of utmost importance - I would agree. Unless I am working with a lobbying firm in a technical capacity, I fail to see how that discussion wouldn't quickly become hostile. And in the end, it also has mostly detrimental effect in poisoning fellow colleagues' communication to you.
If I see or become inadvertently involved in one of those 2 areas, I steer the conversation back to on-topic, or bow out of the conversation. I see no reason to alienate others with my personal practices.
