Some guy at your office annoying you? Does your mother never understand your point of view? Come to me for some well constructed arguments.
My experience in this field includes:
Arguing with hippies: Vaccinations, medicine, crop circles, magic crystals, conspiracy theories.
Arguing with racists: developing countries, colonialism, the bell curve and genetic limitations on intelligence,
Arguing with nationalists: benefits/welfare, immigration
Also argued with anarchists, philosophers, farmers, fundamental Christians etc.
