I'm a forensic criminologist. Our slogan is 'can't run fast enough to be a serial killer so I'll just help the police catch them'.
'I don't care if you're gay, just don't act gay in front of me.' 'I don't mind black people, I just wish they'd keep to themselves.' 'I don't mind your religion, but it's rude to practice it in front of me.' In all three statements, the second half shows that the first half is an obvious lie.
