So too many Americans buy trucks and SUV’s, not because they want to, but because that’s the only thing they can buy.

That is...insanely inaccurate lol. "I wanted to buy a car but I could only find trucks for sale" is not a thing in this country whatosever.

Only replies to the original post will ever be at the top.

"Break the loop and you break the chains."

Nobody actually said that to my knowledge but putting quotes around it lends some legitimacy. 

I apologize and I wouldn't want that either lol. That thought is scary and that meeting would end up with them talking about how to hide my body.

You're right in that the analogy is way off. Here's the only way it would make it right, is if your new date also wanted to vent about your ex. That's probably not the case. But being a Reddit refugee is something in common for many people on Lemmy (especially right now) and so it makes perfect sense for people to talk about it.

Also, I don't give much thought to the posts I scroll past...

Bad analogy, it would be like meeting up with all your ex-girlfriend's other former partners and all bitching about that shared ex because you have that thing in common.

Everything is an opportunity cost. That is, if you're engaging in YouTube you are missing out on something else. It's fine if that's the choice you want to make, but understand that you're "missing out" on hanging out with friends or reading or video games or calling a family member.

This is like asking someone to check in on your ex, sure it sounds like a good idea, but...
