It seems like anytime a person is trying to force a thing on another person they are being a dick. And isn't that what religion is? A group of people who all believe the same thing and who use whatever forces are tolerated by their society to try and push their beliefs and behaviors on others?
It's kind of like if I was on a gluten free diet or some other diet fad or veganism. If I keep my mouth shut about it and just live my lifestyle happily what's the harm? But when somebody crosses the line about their food beliefs and starts to get all pissy and pushy about it doesn't it make you want to hit them? Or at least ridicule them and walk away laughing?
How is religion any different?
