Saying that people who don't share your opinion are "selfish" is a personal attack. You're attacking the person's character rather than their position. You aren't even actually making a case (or bothering to explain) why you think they're selfish. You're simply asserting it as if it were fact.

> You have presented no real counterargument. You have not presented an alternate future.

Counterargument to what? A future that is an alternate to what? None of these things have anything to do with the point I'm making here.

You seem to be wanting to engage in a discussion about something other than what I brought up, and accuse me not engaging in that discussion. I confess, I am not. It's not relevant to my point.
