I'll quote from the comments:
"Show us the next step: first sex."
Person #2 (replying to person #1):
(Engineer) (replying to person #2):
"I'm not supporting [person #1], but why is watching strangers kiss and watching strangers have sex completely polar and opposite? They're both physical expressions of connection to a mate. In my opinion, it's disgusting that someone would let themselves get so tied up in someone for absolutely no reason (assuming it's true that these people are strangers). No matter what the level of physical show, it's all still lying, IMO. You're showing them that you want to derive happiness from doing things with them (are interested in them as a mate), and then you're like, "Nope, you're nobody to me." If they're not nobody's to each other, then it's false that they're two randomly picked people with no connection to each other."
"Oh, and if you say that they went from to randomly picked strangers to two people with a romantic connection, then you're saying that the fact that you have a romantic connection with someone doesn't mean there's anything special about them what so ever, considering you can form a romantic relationship with a random person that did not have to meet any requirements at all."
Of course, on Youtube I always have a more aggressive tone than I would here. I guess I just give into the general tone over in those comments.
Feel free to suggest a thread title. I figured I'd see what discussions arise and then base it off of that.
