What's the distinction between the following pairs of imperatives (ignoring efficacy)?
"Eat more vegetables" vs. "Eat less starch and fat"
"Look both ways before crossing the street" vs. "Don't get hit by a bus"
"Put your hands up" vs. "Don't put your hands down"
"Get enough sleep" vs. "Don't stay up all night"
"Use the toilet" vs. "Don't pee on my house"
"Vote for me" vs. "Don't vote for them"
"Hold it like this" vs. "Don't hold it like that"
"Feel good about yourself and move on" vs. "Don't beat yourself up"
"Take a long walk off a short pier" vs. "Stop badgering me"
'Urging/exhorting people towards' and 'don't deter them from' capture some of the sentiment but they fail to capture the distinction. If I was being meta-ironic, I'd say 'Don't exhort people towards, rather, deter them from'.
