I suppose that's an inaccurate choice of words. I meant to juxtapose something meaningful to someone in stead of the Skygod that the Christians pretend to worship on Sundays.
You said, “the Skygod that the Christians pretend to worship on Sundays”. This comment is uncivil and does not belong here. That behavior is not acceptable and please do not behave this way in the future.
To be clear, the comment denigrates Christians, by (among other things) saying that they pretend to worship.
If you don't call out the hypocrites, how would they ever know they are wrong? Did I cast them in a negative light? Yes. Do they ever read that book of theirs? No.
Your comment seems to be based on some kind of misconception about what religion is. Like, you seem to base your comments on the idea that the Christian bible is the sole foundation for Christian beliefs and practices. There are two problems with that—it’s not true in the first place, and even if it were true, it is not straightforward to interpret the bible.
If you are unwilling to put in the effort to learn what Christianity is, then you should also be unwilling to make comments about whether people are practicing it correctly.
If they're only pretending to believe, they already know they're wrong.
If you sincerely do just want to communicate this to them, I recommend using "God" instead of "Skygod". It doesn't change the message and it makes it sound more like you're speaking in good faith.
