Because it's an annoying job and no one wants to do one more load than they think they have to, so they fill it to the top. If you think four loads is a month's worth of laundry you're either overloading your washer or re-wearing a lot of dirty clothes.
You have enough clothes to wear a whole month without doing laundry? Gee. My entire wardrobe is maybe 4 loads, counting all seasons, and I think I have too many clothes.
The part of that that breaks down is that one group's interpretation of it being okay to kill people isn't necessarily another person's religious practice. Mocking the latter is like treating everyone who eats bacon like a psychopath who enjoys slaughtering animals.
And religion isn't always a choice for everyone. It should be, but isn't always.
It's already an echo chamber. That's just how human interaction is. People aren't going to share unpopular opinions just to be argued with and downvoted. It's not worth it.
Take the recent question about religion. No way am I going to answer that, because I'm not atheist and I know how non-atheists are treated online.
