The person who replied to you went on a rant about voting. Which I agree, religious people tend to vote against their interests. But spending 3 paragraphs talking about voting and nothing else doesn't really elaborate on why it's a shit lifestyle does it? I'll add what I think are the worst aspects of a religious lifestyle.

The biggest issue with a religious lifestyle, in my opinion, is the fact that truly believing in a religion, especially a deity means you have been convinced, and are able to convince yourself to believe in something for which there is no evidence (ive heard religious arguments that faith is a "radical" belief in something that defies logic). The concept of God, for the most part, isn't that bad. The issue is, if you've let in one truth about your life that you believe is true despite any supporting evidence and no logical reason, that opens the door for more random beliefs that aren't founded on evidence. Or more accurately, they may believe new things (good or bad) for one reason or another but the idea that something needs evidence or solid reasoning to be believed doesn't factor into their calculations nearly as much.

This means that a religious lifestyle is random, based on where and how they were raised with an ethos of not questioning their foundational beliefs. This means many religious communities grow up fine, and it means many grow up in the bizarre bigoted looney-tunes world I'm sure you've seen if you know religious people from disparate backgrounds.

Idk exactly what that person necessarily meant, but to me, a lifestyle based on beliefs that the person has been trained not to question and doesn't need evidence to be true is kind of shit.

And in before people say that not all (or even most) religious people are like that. I agree that a religious person could easily be raised as someone who engages in logical reasoning and only accepts new beliefs if they think they have sufficient evidence etc. That's probably true. I'm explaining why I think religion opens the door to a shit lifestyle because of religion.
